Sync of Domain Users with more than 30.000 users failed
Last modified: 2013-11-19 06:41:22 CET
The sync of Domain Users from S4 to UCS failed. In this case the group Domain Users has more than 30.000 users. The connector-status file shows an "Can't contact LDAP server", maybe idle timeout: 19.08.2013 23:47:22,165 LDAP (PROCESS): sync from ucs: [ user] [ modify] cn=v2xvguuvzd,cn=users,dc=school30000,dc=local 19.08.2013 23:47:33,265 LDAP (PROCESS): sync to ucs: [ user] [ modify] uid=v2xvguuvzd,cn=users,dc=school30000,dc=local 19.08.2013 23:47:34,344 LDAP (PROCESS): sync to ucs: [ group] [ modify] cn=domain users,cn=groups,dc=school30000,dc=local 20.08.2013 00:26:36,890 MAIN (------ ): DEBUG_INIT 20.08.2013 00:26:36,908 LDAP (PROCESS): Building internal group membership cache 20.08.2013 00:26:39,952 LDAP (PROCESS): Internal group membership cache was created 20.08.2013 00:26:48,715 LDAP (PROCESS): sync to ucs: [ user] [ modify] uid=v2xvguuvzd,cn=users,dc=school30000,dc=local 20.08.2013 00:26:50,32 LDAP (PROCESS): sync to ucs: [ group] [ modify] cn=domain users,cn=groups,dc=school30000,dc=local 20.08.2013 01:06:48,574 LDAP (PROCESS): sync to ucs: [ user] [ modify] uid=v2xvguuvzd,cn=users,dc=school30000,dc=local 20.08.2013 01:06:49,983 LDAP (PROCESS): sync to ucs: [ group] [ modify] cn=domain users,cn=groups,dc=school30000,dc=local 20.08.2013 01:44:26,625 LDAP (PROCESS): sync to ucs: [ user] [ modify] uid=v2xvguuvzd,cn=users,dc=school30000,dc=local 20.08.2013 01:44:27,781 LDAP (PROCESS): sync to ucs: [ group] [ modify] cn=domain users,cn=groups,dc=school30000,dc=local 20.08.2013 02:21:39,279 LDAP (PROCESS): sync to ucs: [ user] [ modify] uid=v2xvguuvzd,cn=users,dc=school30000,dc=local
I've discovered two points in the code where a re-open of the connection is needed. Code: r43498 Changelog: r43499
This is tested by the automated jenkins tests. A setup with 1000 users and 30 groups (each group has all users as members) was successfully synchronized. Changelog OK
