Re: N-way multimaster replication problem



Hi,

Okay, i found the bug.
It was about the olcServerID.
My cn=config showed olcServerID: 1 ldap://alpha-int/, olcServerID: 2
ldap://beta-int/, which is correct.
But if I start my openldap as ubuntu says (/usr/sbin/slapd -h
ldap://beta-int/ ldap://127.0.0.1:389/ <http://127.0.0.1:389/> ldapi:///
-g openldap -u openldap -F /etc/ldap/slapd.d/), it does not recognise
that he is beta-int. Only if I start it with only the ldap://beta-int/
parameter. But I really need the other two interfaces as well.
What can I do now with it?

What version of OpenLDAP are you using?

A bug similar to this was corrected in 2.4.18:
http://www.openldap.org/its/?findid=5942

If you're using an older version, this should still work fine so long as the URL in the -h option to slapd exactly matched the URL in serverID (make sure the all slashes are present, etc).

Preferably, use the latest release, though, to avoid other such bugs now fixed :)

    Hi,

    I have just set up openldap on two nodes (alpha, beta). I am using
    openldap for a passdb backend for samba.
    I followed this guide:
    http://www.openldap.org/doc/admin24/replication.html#N-Way%20Multi-Master

    To a point, everything seems to work just fine, the cn=config
    replication works both ways.
    After deleting everything from my base, I run smbldap-populate on
    the node alpha.
    It creates the default users, groups pretty fine, but it failed to
    replicat to node beta.

    the log entries shows this on alpha:
    http://pastebin.com/Ykhvq4BY

    on the other node the log shows this on beta:
    http://pastebin.com/KNwgHQDW

    My configuration looks the following:

    cn=config:
    http://pastebin.com/mT5A4K5i

    olcDatabase={0}config,cn=config:
    http://pastebin.com/kwBNEaeV

    olcDatabase={0}hdb,cn=config:
    http://pastebin.com/FsPaKK90

    I have the olcOverlay={0}syncprov,olcDatabase={0}config,cn=config
    and olcOverlay={0}syncprov,olcDatabase={1}hdb,cn=config set to
    olcOverlay: {0}syncprov

    I have nothing in slapd.conf
    Do you know where to search this problem? What other logs should i
    attach to figure it out?

    Have a nice day,
    Best Regards,
    Marton, Neher
