This looks like a pretty high risk, even if ipabak says everything
is fine.

The major problem was the failure on Debian Wheezy using the very old
sssd. This seems to be gone now by resolving the "easy" cases.

About the "hard" cases: AFAICS

ipaservers+nsuniqueid=109be302-ccd911e6-a5b3d0c8-d8da17db,cn=hostgroups,cn=accounts,dc=example,dc=de

doesn't list any hosts (the official entry does), and

cn=ipaservers+nsuniqueid=109be304-ccd911e6-a5b3d0c8-d8da17db,cn=ng,cn=alt,dc=example,dc=de

points to the duplicate entry only. They are not referenced anywhere
else in the ldap database. So I would suggest to wait and see if
I run in any problem here. Would you agree to this, or do you expect
problems later?


I highly appreciate your help

Harri
