So does anyone have any more suggestions? Or should I just configure a

Thanks,

I've seen the initial problem where the memberof elements stop updating
on
my own FreeIPA v1 replica as well. Normally it happens after I perform
a
full init of the replica. The subsequent errors you are experiencing
have
not occurred on my system. You have not indicated a synchronization
error
anywhere, but they tend to get buried in the error logs. I assume you
are
not short on disk space on the replica. I also assume that the /var has
not
been mounted as read-only. (I've had a few oddities where disk/storage
problems have caused a file-system to be remounted read-only recently)
Out of curiosity, if you modify a user on the replica, do the changes
get
saved to the record? If you add a user to a new group on the replica
does
the memberof attribute get added to the user's record?
Hmm, very strange. Adding my user to another group appears to have
fixed the memberOf attributes for my user on the replica....
Presumably, the fixup-memberof.pl script is supposed to do this -
strange that it does not appear to work.
I can create a temporary group, add all users to it and then remove
them again - possibly that would fix the problem?
I'm still a little concerned by log entries such as (on the replica):
NSMMReplicationPlugin - replica_check_for_data_reload: Warning: data
for replica dc=example,dc=com was reloaded and it no longer matches
the data in the changelog (replica data> changelog). Recreating the
changelog file. This could affect replication with replica's consumers
in which case the consumers should be reinitialized.
You should only see this once. This is ok for an initial initialization
or
a reinitialization.
OK, thanks. I also get the following (on both master and replica) on
each alteration of LDAP:
NSMMReplicationPlugin - repl_set_mtn_referrals: could not set
referrals for replica dc=example,dc=com: 20
Is this expected/normal?
Thanks,
Dan

I was going to suggest reinitializing the sync agreement and running the
fixmemberof script again. Did I miss that you have actually done that
already?
Yes, once I realised that there were difference between the master and
replica I ran:
ipa-replica-manage init ohm.example.com
from curie. To try and get the syncing working.
If not than that error seems pretty out of place. Before you do run
the following script on both servers (replacing dc=example and hostname) and
remove the admin group from any that you find on both servers before doing
your re-init.
ldapsearch -Y GSSAPI -h hostname -b
"cn=groups,cn=accounts,dc=example,dc=com"
'(member=cn=admins,cn=groups,cn=accounts,dc=example,dc=com)'
I did have a group which contained the admins group as a member. I
removed this yesterday and so there are now no groups containing the
member 'admins'.
The test of adding the user to the group was only to test that the
ipa-memberof plug-in is functioning properly on the replica. It is triggered
by a group change on the server. The fixmemberof script is really a much
more efficient way of updating all accounts.
Yes, but the fixmember script doesn't appear to work. It appeared to
successfully add the entry:
cn=memberOf_fixup_2010_10_8_15_6_11
but the memberOf attributes weren't corrected.
The way that the memberOf fixup task works is that a search is performed
using the specified search base and optional filter that are supplied
when the task is created. Each matching entry has it's memberOf
attribute values removed and the memberOf values are re-computed.
The reason that the task did not work for you is that you set the base
for the fixup task to "cn=groups,cn=accounts,dc=example,dc=com". This
search base does not contain any of your user entries, so noe of them
had their memberOf attribute re-computed. The search base needs to
contain your user entries that you want fixed up.
-NGK
One other consideration, are both server time in sync (at least within 5
minutes) but in general, you want them to be pretty close.
Yes, they are both in sync ('Exactly' in sync,< 1s apart as far as I can tell).
Thanks for your help.
Dan
