Great answer! Didn't know that application. Thank you so much! Nice app - do you know any alternatives for it on Mac? Note, if you don't know your full bind DN, you can also just use your normal username or email with -U ldapsearch -v -h contoso. Thanks for your reply. What I'm really looking for is a tool where I can type the user DN, and password, and the tool would test and see if the user can be authenticated with those credentials.
This is a very easy tool to develop; so I was hoping that there is already such a tool. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.

You can write an easy vbscript function which can verify this Please note this will lock an account out after 'n' amount failed logins, 'n' being whatever policy you have set. This should always be true of any solution which you use. Tomasz Modelski Tomasz Modelski 1 1 bronze badge. I assume you're suggesting the initial "Connect to Active Directory" prompt as the password test case - that seems to do the job from my testing.
Incorrect password results in a "username or password is incorrect" prompt fairly quickly, so this would be a decent GUI-based test to work through a mental list of possible passwords.

I'm talking about a tool that can tell me if the password I enter for a particular account is that account's password. TheCleaner: Sure, you can create a word-list with all possible passwords for a specific account and use this list for a set of accounts. Testing with SMB or something is a rather bad idea. It fills your logs, messes up sessions to the file server, generates load on DCs and file servers and so on.
Using code from above, check all domain accounts to see if they are using a certain password. Operdale Operdale 1 1 1 bronze badge. Dom Dom 6, 1 1 gold badge 18 18 silver badges 24 24 bronze badges.

The more access any one group or user has, the higher the chance the access can be abused. In other words, the less access you give each user and group, the safer you keep your systems as a whole. Make use of tools. One important step you can take to make sure your Active Directory is set up correctly is to use high-quality professional tools.
A centralized solution like SolarWinds Access Rights Manager will help you to effectively manage your Active Directory configurations and permissions. ARM includes several features specifically designed for managing Active Directory, including tools to simplify Active Directory delegation, tools for group management , and permissions reporting. Additionally, the Active Directory Auditing Tool helps ensure security and compliance. These features make sure your AD setup is both secure and efficient.
SolarWinds allows you to do this by downloading a day free trial of ARM. The test returns the results along with group and attribute details authorization information that can be viewed on the Admin Portal. Any subject or alternative name attributes in the certificate for Active Directory only option—You can use this option to use Active Directory UPN as the username for logs and try all subject names and alternative names in a certificate to look up a user.
This option is available only if you choose Active Directory as the identity source. You can have multiple identities from TLS certificates. You can use this page to view the status of the join points on each node in the Cisco ISE deployment. The node view is a read-only page and provides only the status.
This page does not support any join, leave, or test option. However, it provides a link for each join point to the main join point page, where these operations can be performed. This page also shows the last diagnostics status and a link to diagnostics tool. The advanced tuning feature provides node-specific changes and settings to adjust the parameters deeper in the system.
This page also provide troubleshooting options like disable encryption. These settings are not intended for normal administration flow and should be used only under Cisco Support guidance. This section describes the manual steps necessary in order to configure Active Directory for integration with Cisco.
However, in most cases, you can enable Cisco to automatically configure Active Directory. The following are the prerequisites to integrate Active Directory with Cisco. If you want to query other domains from a specific join point, ensure that trust relationships exist between the join point and the other domains that have user and machine information to which you need access. If trust relationships does not exist, you must create another join point to the untrusted domain. For more information on establishing trust relationships, refer to Microsoft Active Directory documentation.
You must have at least one global catalog server operational and accessible by Cisco , in the domain to which you are joining Cisco. For the account that is used to perform the join operation, the following permissions are required:. Search Active Directory to see if a Cisco machine account already exists. Create Cisco machine account to domain if the machine account does not already exist. Set attributes on the new machine account for example, Cisco machine account password, SPN, dnsHostname.
For the account that is used to perform the leave operation, the following permissions are required:. If you perform a force leave leave without the password , it will not remove the machine account from the domain. For the newly created Cisco machine account that is used to communicate to the Active Directory connection, the following permissions are required:. Query some parts of the Active Directory to learn about required information for example, trusted domains, alternative UPN suffixes and so on.
You can precreate the machine account in Active Directory, and if the SAM name matches the Cisco appliance hostname, it should be located during the join operation and re-used. If multiple join operations are performed, multiple machine accounts are maintained inside Cisco , one for each join.
The credentials used for the join or leave operation are not stored in Cisco. Only the newly created Cisco machine account credentials are stored, and this is in order to enable the Endpoint probe to run as well. DNS recursion can have significant negative impact on performance. Avoid using DNS servers that query the public Internet. They can cause delays and leak information about your network when an unknown name has to be resolved.
You can check these parameters by running the Domain Diagnostic tool. A pop-up appears asking if you want to join the newly created join point to the domain. Click Yes if you want to join immediately. If you clicked No , then saving the configuration saves the Active Directory domain configuration globally in the primary and secondary policy service nodes , but none of the Cisco ISE nodes are joined to the domain yet. You must do this explicitly even though you saved the configuration.
To join multiple Cisco ISE nodes to a domain in a single operation, the username and password of the account to be used must be the same for all join operations. If different username and passwords are required to join each Cisco ISE node, the join operation should be performed individually for each Cisco ISE node. The user used for the join operation should exist in the domain itself. If it exists in a different domain or subdomain, the username should be noted in a UPN notation, such as jdoe acme.
Cisco ISE creates the machine account under the specified organizational unit or moves it to this location if the machine account already exists. If the organizational unit is not specified, Cisco ISE uses the default location. The value should be specified in full distinguished name DN format. The syntax must conform to the Microsoft guidelines. If the machine account is already created, you need not check this checkbox.
You can also change the location of the machine account after you join to the Active Directory domain. You can select more than one node to join to the Active Directory domain. If the join operation is not successful, a failure message appears. Click the failure message for each node to view detailed logs for that node. You must ensure that this process is allowed to complete.
Refer to the following Microsoft Active Directory documentation for troubleshooting information:. If you no longer need to authenticate users or machines from this Active Directory domain or from this join point , you can leave the Active Directory domain. When you reset the Cisco ISE application configuration from the command-line interface or restore configuration after a backup or upgrade, it performs a leave operation, disconnecting the Cisco ISE node from the Active Directory domain, if it is already joined.
We recommend that you perform a leave operation from the Admin portal with the Active Directory credentials because it also removes the node account from the Active Directory domain. This is also recommended when you change the Cisco ISE hostname.
If you leave the Active Directory domain, but still use Active Directory as an identity source for authentication either directly or as part of an identity source sequence , authentications may fail. To delete the Cisco ISE machine account from the Active Directory database, the Active Directory credentials that you provide here must have the permission to remove machine account from domain.
The Active Directory administrator must manually remove the machine account that was created in Active Directory during the time of the join. The domain to which Cisco ISE is joined to has visibility to other domains with which it has a trust relationship. By default, Cisco ISE is set to permit authentication against all those trusted domains.
You can restrict interaction with the Active Directory deployment to a subset of authentication domains. Configuring authentication domains enables you to select specific domains for each join point so that the authentications are performed against the selected domains only. Authentication domains improves security because they instruct Cisco ISE to authenticate users only from selected domains and not from all domains trusted from join point. Authentication domains also improve performance and latency of authentication request processing because authentication domains limit the search area that is, where accounts matching to incoming username or identity will be searched.
It is especially important when incoming username or identity does not contain domain markup prefix or suffix. Due to these reasons, configuring authentication domains is a best practice, and we highly recommended it. A table appears with a list of your trusted domains. By default, Cisco ISE permits authentication against all trusted domains. Cisco ISE machine account must have permission to read tokenGroups attribute. This attribute can contain approximately the first groups that a user may be a member of the actual number depends on Active Directory configuration and can be increased by reconfiguring Active Directory.
If a user is a member of more groups than this, Cisco ISE does not use more than the first in policy rules. You must configure Active Directory user groups for them to be available for use in authorization policies. SID provides accurate group assignment matching. If you delete a group and create a new group with the same name as original, you must click Update SID Values to assign new SID to the newly created group.
After an upgrade, the SIDs are automatically updated after the first join. You must configure Active Directory user and machine attributes to be able to use them in conditions in authorization policies. When you enter an example username, ensure that you choose a user from the Active Directory domain to which the Cisco ISE is connected.
The example value displayed when you retrieve attributes are provided for illustration only and are not stored. The Test User tool can be used to verify user authentication from Active Directory. You can also fetch groups and attributes and examine them. You can run the test for a single join point or for scopes. You can join the same forest more than once, that is, you can join more than one domain in the same forest, if necessary. Cisco ISE now allows to join domains with one-way trust.
This option helps bypass the permission issues caused by a one-way trust. You can join either of the trusted domains and hence be able to see both domains.
It has an associated dictionary for attributes and groups, which can be used in authorization conditions. Scope—A subset of Active Directory join points grouped together is called a scope. You can use scopes in authentication policy in place of a single join point and as authentication results.
Scopes are used to authenticate users against multiple join points. Instead of having multiple rules for each join point, if you use a scope, you can create the same policy with a single rule and save the time that Cisco ISE takes to process a request and help improve performance.
A join point can be present in multiple scopes. A scope can be included in an identity source sequence. You cannot use scopes in an authorization policy condition because scopes do not have any associated dictionaries. It is only visible as an authentication result in policy and identity sequences.
Cisco ISE allows you to define multiple Active Directory join points, where each join point represents a connection to a different Active Directory domain. Each join point can be used in authentication and authorization policies and in identity sequences, as a separate identity store. Join points can be grouped to form a scope that you can use in authentication policy, as authentication results, and in identity source sequences.
You can select individual join points as the result of authentication policy or identity source sequences, when you want to treat each join point as a completely independent group of policy.
For example, in a multi-tenant scenario, where the Cisco ISE deployment supports independent groups with their own network devices, network device groups can be used for selection of the Active Directory domain. However, if Active Directory domains are regarded as part of the same enterprise without any trust between the domains, you can use scopes to join multiple disconnected Active Directory domains and create a common authentication policy.
You can thus avoid the need for every join point represented by a different identity store to be defined in the authentication policy and to provide duplicate rules for each domain.
