Description Sönke Schwardt-Krummrich univentionstaff 2025-02-27 16:51:24 CET 
When joining a (UCS@school) 5.2 replica, the join.log contains the following output:

Configure 20univention-join.inst Thu Feb 27 16:24:37 CET 2025
2025-02-27 16:24:37.965358922+01:00 (in joinscript_init)
chown: warning: '.' should be ':': „root.DC Backup Hosts“
Object modified: cn=dcmitte,cn=dc,cn=server,cn=computers,ou=gsmitte,dc=ucs,dc=intra

Currently the chown warning is only an optical issue.

Comment 3 Florian Best univentionstaff 2025-04-01 11:55:32 CEST 
Reproduce:
chgrp root /etc/univention/ssl/master521.school.dev/req.pem
univention-run-join-scripts --force --run-scripts 20univention-join.inst

Fixed in:

univention-join.yaml
1a8edf630275 | feat(join): make use of chown future proof

univention-join (14.0.7)
1a8edf630275 | feat(join): make use of chown future proof
    prevent the warning `chown: warning: '.' should be ':': „root.DC Backup Hosts“` in `20univention-join.inst` when any file under /etc/univention/ssl belongs to the group `root`.
