I've setup both the Active Directory and LDAP Realm but I'm struggling to get these imported accounts signed in to the cluster on 9.2.3.

Here's an example of an LDAP configuration I've stood up even though I've done both AD and LDAP.

The Realm was the same as the domain name and setup as not to try and figure this out

Sync Options
Bind User: CN=Prox,OU=Network,DC=XX,DC=XX
e-mail attribute: mail
User Classes: user, person
User Filter: (&(MemberOf=CN=Proxmox,OU=Security Groups,DC=XX,DC=XX))

Some of the data has been made hidden or obscured for obvious reasons.

I am able to sync the correct users that I want within the environment, these accounts are enabled, I've also tried them in all lowercase and case sensitive as needed for the username, I did try the username, full username, and domain\username (none worked), reset my account password we assigned to access this system due to potential lockout/password reset window.

No matter which method I set whether its the Active Directory or LDAP for realm configuration get this for LDAP and a similar for AD.

Hoping someone can provide me with assistance because this has been going on for several hours trying to figure this out.
