Our server is spamming an alarm for Invalid Credentials on LDAP sync but I can't figure out what is wrong in my LDAP setup. It was previously working and I just recently noticed the alarms. I have made the user a domain admin, I have reset its password in the domain. I'm at a loss and any help would be appreciated.

LDAP.ConnectionString      ldap://{dc server}:389
LDAP.GroupClass              group
LDAP.GroupUniqueID        objectGUID
LDAP.SeachBase              {OU of users in domain}
LDAP.SearchFilter              (objectClass=*)
LDAP.SyncUser                {distingushed name of user in domain}
LDAP.SyncUserPassword    {sync user password}
LDAP.UserClass                user
