Hi all! I have a serious problem! I try to configure the ldap server mirroring mode, but something problem with this. Fist of all: I tested the mirroring on two openldap 2.4.11-0ubuntu6.1. and it worked fine. I just configured slapd.conf file like this: # Global section serverID 1 (another ldap is 2) moduleload syncprov overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 syncrepl rid=001 provider=ldap://192.168.1.2 type=refreshAndPersist interval=00:00:00:10 searchbase="dc=test,dc=hu" filter="(objectClass=*)" attrs="*" scope=sub schemachecking=off bindmethod=simple binddn="cn=admin,dc=test,dc=hu" credentials="test" retry="60 +" mirrormode on It was okay, when I modified the db1, the db2 modified too. BUT! I try to set up on version 2.3.30, I use the same configuration, the ldap starts good, but when i try to modify the db, the phpldapadmin shows this error: Could not perform ldap_modify operation. LDAP said: Server is unwilling to perform Error number: 0x35 (LDAP_UNWILLING_TO_PERFORM) Description: The LDAP server refused to perform the operation. What is the problem, what is missconfigured? please help, thank you! br Gabor
