Hi,

When I configure N-Way Multi-Master configuration with cn=config, slapd terminates with the error: "module syncprov.la: null module registered" and "read_config: no serverID / URL match found. Check slapd -h arguments".

olcServerID IDs are already added and configured properly, but when slapd starts with -h option, it always fails.

Please help if someone has gone through a similar issue.

Thanks,

Joe

Is there an equivalent /etc/sysconfig/ldap file in Solaris 10?

Platform: Sun Solaris10

OpenLDAP: openldap-2.4.32

Configuring for N-Way Multi-Master: adding olcServerID, olcOverlay: syncprov, and olcSyncRepl:

apggd04dev# more config_repl.ldif
#Specify ServerID for both the masters
dn: cn=config
changetype: modify
add: olcServerID
olcServerID: 101 ldap://apggd06dev.pg.dtveng.net
olcServerID: 201 ldap://apggd04dev.pg.dtveng.net

#Enable Syncprov Overlay for config database
dn: olcOverlay=syncprov,olcDatabase={0}config,cn=config
changetype: add
objectclass: olcOverlayConfig
objectclass: olcSyncProvConfig
olcOverlay: syncprov

#Configure SyncRepl for config database
dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcSyncRepl
olcSyncRepl: rid=001 provider=ldap://apggd06dev.pg.dtveng.net binddn="cn=config" bindmethod=simple
credentials=secret searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=1
olcSyncRepl: rid=002 provider=ldap://apggd04dev.pg.dtveng.net binddn="cn=config" bindmethod=simple
credentials=secret searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=1
-
add: olcMirrorMode
olcMirrorMode: TRUE

apggd04dev# ldapmodify -x -D "cn=config" -w secret -f config_repl.ldif -h apggd04dev.pg.dtveng.net <== olcServerID IDs are already added successfully to dn: cn=config.
modifying entry "cn=config"
adding new entry "olcOverlay=syncprov,olcDatabase={0}config,cn=config"
modifying entry "olcDatabase={0}config,cn=config"

Restart slapd with -h option:
