The problem appears to be related to the users, rather than the
groups. None of the users on ohm have a 'memberOf'. Curie has the
correct memberOf attributes.

The error message specifically mentions the admin group:

- Entry "cn=admins,cn=groups,cn=accounts,dc=example,dc=com" --
attribute "memberOf" not allowed

As if it is attempting to add the memberOf attribute to the group entry
cn=admins,cn=groups,cn=accounts,dc=example,dc=com - I don't know why it
would do this unless it is attempting some sort of group nesting.
This is still a mystery - we need to figure out why it is attempting to add memberOf to this entry.
The groups themselves appear to be correct on both servers. Both ohm
and curie have groups which contain the correct 'member' attributes.
So the problem appears to be that ohm contains groups with correct
'members', but none of the users have any 'memberOf's.


Do all of the users have the inetUser objectclass?

Yep. Looks like it. I have 162 users:

[djscott ohm ~]$ ldapsearch -h curie.example.com -x -b
'cn=users,cn=accounts,dc=example.com' |grep 'objectClass: inetUser'|wc
    162     324    3564
[djscott ohm ~]$ ldapsearch -h ohm.example.com -x -b
'cn=users,cn=accounts,dc=example,dc=com' |grep 'objectClass:
inetUser'|wc
    162     324    3564
[djscott ohm ~]$
If you run the lib/dirsrv/slapd-ds/fixup-memberof.pl script, does it add the memberOf attributes?
Thanks,

Dan

Hi,

ohm_admins.ldif and curie_admins.ldif attached. I added a '-h
$hostname' to the command to ensure that I queried both servers. The
results look identical to me, apart from the ordering.

Thanks,

Dan

Hi,

I have master and slave FreeIPA servers. I recently upgraded the
slave
by wiping, re-installing Fedora 13 and re-creating the replication
using ipa-replica-prepare and ipa-replica-install.

For some reason, the slave is having difficulty replicating the
memberOf attribute. I can attach an LDAP viewer to the replica, and
view the schema, but the memberOf attributes are missing. Also, the
master server contains the lines:

- Entry "cn=admins,cn=groups,cn=accounts,dc=example,dc=com" --
attribute "memberOf" not allowed
NSMMReplicationPlugin - repl_set_mtn_referrals: could not set
referrals for replica dc=example,dc=com: 20
NSMMReplicationPlugin - replica_reload_ruv: Warning: new data for
replica dc=example,dc=com does not match the data in the changelog.
 Recreating the changelog file. This could affect replication with
replica's  consumers in which case the consumers should be
reinitialized.
[06/Oct/2010:09:58:33 -0400] - skipping cos definition cn=account
inactivation,cn=accounts,dc=example,dc=com--no templates found

The rest of the replication appears to be working correctly (as far
as
I can tell).

I have tried using ipa-replica-manage init and synch to try to fix
the
replication, but I suspect this has something to do with the schema
definition.

Does anyone have any pointers/ideas for how I can fix this?


Dan, the memberof attribute is explicitly not replicated, and should
be
simply re-generated on the receiving replica when "member" attributes
are replicated.


So does this imply that there is some corruption in the schema on the
replica server?



Are the IPA versions on the master and the replica the same ?


They are both the same version: ipa-server-1.2.2-4.fc13.x86_64

Thanks,

Dan Scott


It is complaining that memberOf isn't allowed in the admins group which
is
pretty strange.

Can you show us the admins group out of the replica and master?

ldapsearch -x -b 'cn=groups,cn=accounts,dc=example,dc=com' cn=admins


Neither one has the inetUser objectclass which allows the use of
memberOf.
 But why is it attempting to add memberOf to this entry which is itself a
group entry?  Is this some sort of nested group?

thanks

rob
