Description Fabian Schneider

UCS offer script to automatically join Ubuntu Clients to existing UCS Domains:
https://github.com/univention/univention-domain-join

Since Ubuntu 20.04 the script uses ldapwhoami in order to detect the full dn of the Join-User:
https://github.com/univention/univention-domain-join/blob/ubuntu20.04/univention_domain_join/join_steps/ldap_configurator.py#L140

This does not work on Univention Primary Servers, that are in AD Member Mode with the following error message:

$ ldapwhoami -QY GSSAPI
ldap_sasl_interactive_bind_s: Local error (-2)
additional info: SASL(-1): generic failure: GSSAPI Error: Miscellaneous failure (see text) (Matching credential (ldap/ucs-admem.example-ad.org@EXAMPLE-AD.ORG) not found)
