Problem:
I am using a personalized admin user or alternative join user to join another system to the domain but something won’t work.
Solution:
Whatever user you use to join a system, be sure it is member in the following groups
- Domain Admins
- Domain Users
- DC Backup Hosts
To add a user to a group you simply might use udm on console
root@ucs:~# udm users/user modify --dn "uid=<JOIN-USER>,cn=users,$(ucr get ldap/base)" \
--append "groups=cn=DC Backup Hosts,cn=groups,$(ucr get ldap/base)"
