vCenter Single Sign-On error

Jump to solution

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.

After checking the log files I was able to determine that the issue was being caused by a user in the LDAP directory that didn't have one of the attributes required.

delete and re-create the LDAP authentication and use auto detect of LDAP option.

What do you mean when you say to use auto detect of LDAP options?

Hi OwenK,

My vCenter has exactly the same issue, could you please share a little bit more detail about which attribute caused the problem? Thanks a lot for the help!

Best Regards,

Andong

Has anyone else had this issue? It seems to happen with my vCenter sporadically and I'm not sure what OP means by a user not having the correct attributes. Thanks!
