Some customers are setting up the Apstra AD integration to allow AD or LDAP authentication when accessing the Apstra Web UI, as documented here: https://www.juniper.net/documentation/us/en/software/apstra5.0/apstra-user-guide/topics/topic-map/provider-ad.html. 

Some customers may see the following issue when trying the "Check provider settings" after deploying the AD/LDAP external provider in the Apstra controller. 

This error is normally related to the Bind information provided to the Apstra controller during the AD/LDAP external provider deployment. This Bind information is supplied in the field named "Bind DN". To fix possible Bind miss information, the customers need to make sure that the Bind DN information has the exactly same information (in this case the bind information is case sensitive) present in the AD Account extensions "distinguishedName" name field as below:

AD distinguishedName information present in the user account extensions.

Asptra AD/LDAP external provider bind information.
