Hi people,

I'm trying to get replication working between two OpenLDAP 2.0.23
Servers (also tested with 2.0.27, same problem). If I change an entry
on the master, the changes are commited to the slave. But I ran into
problems when chaning an entry on the slave.

Configuration followes:

,----[ master slapd.conf ]
| rootpw "foo"
| updatedn "cn=admin,dc=bzimage,dc=de"
| replica host=slave.bzimage.de:389
|         binddn="cn=admin,dc=bzimage,dc=de"
|         bindmethod=simple
|         credentials=foo
`----

,----[ slave slapd.conf ]
| rootdn "cn=admin,dc=bzimage,dc=de"
| rootpw "foo"
| updatedn "cn=replica,dc=bzimage,dc=de"
| updateref "ldap://master.bzimage.de:389/";
`----

The entry I wanted to change:

,----
| dn: cn=tretkowski,ou=people,dc=bzimage,dc=de
| objectClass: inetOrgPerson
| objectClass: posixAccount
| objectClass: top
| objectClass: shadowAccount
| objectClass: organizationalPerson
| objectClass: inetLocalMailRecipient
| uid: tretkowski
| cn: Norbert Tretkowski
| sn: Tretkowski
| givenname: Norbert
| userpassword: foo
| loginShell:/bin/zsh4
| uidnumber:1000
| gidnumber:100
| homeDirectory: /home/tretkowski
`----

The slave redirectes the client to the master. There, I get the
following error message in the log:

Every time, I try to edit a value on the slave, I run into this error.
As I said, changing it on the master is no problem, then the changes are
correct comitted to the slave(s).

Any suggestions are welcome.
