Subject: [PATCH] Upgrade: fix replica agreement
The upgrade checks the replication agreements to ensure that
some attributes are excluded from replication. The agreements
are stored in entries like
cn=serverToreplica,cn=replica,cn=_suffix_,cn=mapping tree,cn=config
but those entries are managed by the replication topology plugin
and should not be updated directly. The consequence is that the update
of the attributes fails and ipa-server-update prints an error message:
Error caught updating nsDS5ReplicatedAttributeList: Server is unwilling
to perform: Entry and attributes are managed by topology plugin.No direct
modifications allowed.
Error caught updating nsDS5ReplicatedAttributeListTotal: Server is
unwilling to perform: Entry and attributes are managed by topology
plugin.No direct modifications allowed.
The upgrade continues but the replication is not excluding
passwordgraceusertime.
Instead of editing the agreements, perform the modifications on
the topology segments.
