Troubleshooting Active Directory Authentication

One of the most common causes of issues in Active Directory configuration is simply not having the correct settings. It’s useful when trying to diagnose AD LDAP issues to have an LDAP browser to hand. Using an LDAP browser you can test the Base DNs you’re using and the credentials used to connect to the LDAP store, then drill into how your AD/LDAP store is organised to, for example, view the attributes your AD store is using, check name hierarchies (useful for diagnosing Base DN issues) etc

We can use LDAP browsers such as Apache Directory Studio or JXplorer that are free to use for testing the LDAP credentials.
