I am running the vCenter Server Appliance version 6.7 and I am using LDAP for authentication. When I first set up vCenter the LDAP authentication was working perfectly fine and continued to do so up until sometime last week. The problem that I am having is that under the users and groups tab when I select my LDAP domain I get the error "A vCenter Single Sign-On service error occurred" and I am unable to see any of the users. However, I am still able to log in to all of the LDAP user accounts without any errors. I am also unable to set permissions on objects by user but I am still able to add the users to groups.
I am using the vCenter Server Appliance version 6.7 running on ESXi version 6.7. I am using Open LDAP for authentication. I have both forward and reverse DNS records set up for both the vCenter server and the LDAP server. I have tried re installing vCenter Server to fix the problem as well as trying a different LDAP server, both of which did not solve the problem.
Any help with this would be greatly appreciated.
