Of course they are not identical :-(. Worst case seems to be this
one:

% ldapsearch -o ldif-wrap=no -D "cn=directory manager" -w secret -b "cn=DNS Servers+nsuniqueid=109be317-ccd911e6-a5b3d0c8-d8da17db,cn=privileges,cn=pbac,dc=example,dc=de" -s base

Looks like the wrong record has been marked as a duplicate. Can I just copy
the missing "memberOf" attributes to the good record, delete the bad record,
and all is fine?


Next ldapmodify returned these error messages:

	deleting entry "cn=ipaservers+nsuniqueid=109be304-ccd911e6-a5b3d0c8-d8da17db,cn=ng,cn=alt,dc=example,dc=de"
	ldap_delete: Server is unwilling to perform (53)
	        additional info: Deleting a managed entry is not allowed. It needs to be manually unlinked first.


	deleting entry "cn=ipaservers+nsuniqueid=109be302-ccd911e6-a5b3d0c8-d8da17db,cn=hostgroups,cn=accounts,dc=example,dc=de"
	ldap_delete: Operations error (1)


I am highly concerned especially about the "Operations error". Sounds
like something internal.


Every helpful comment is highly appreciated.
