PowerFlex LDAP authentication fails when using a third-party multi-factor authentication (MFA) for Active Directory (AD).

• Failed Authentication Attempts: Users cannot authenticate in PowerFlex using LDAP credentials.
• No Issues with Direct AD Authentication: Users might be able to authenticate directly with Active Directory without any issues, but the problem arises when they use LDAP through PowerFlex.

Primary MDM (PMDM) trc log would show similar outputs like this:

scli --login --username sio@sio.lab --password 'Scaleio123!' --ldap_authentication
Error: MDM failed command. Status: user authentication on LDAP service failed. Please check username and password.

A potential workaround is to point the LDAP authentication directly to the domain controller when creating the LADP service using SCLI. By doing this, you can bypass any potential blockages or issues caused by third-party balancers.

You must delete and re-create the LDAP service to point it directly to the domain controller using SCLI.
