A Tricky Problem of IBM Directory Server v6.1

I’ve been tortured by this LDAP server for a few days and finally get over it. The scenario is based on Windows XP.
To get IDS running, you have to remove any DB2 instances you installed before. It seems that it can only work with the DB2 instance it provides. For a pre-installed DB2 V9.5 instance, the IDS will report that “GLPSRV064E Failed to initialize be_config”. Secondly, when you create your LDAP instance, use your main OS account (the one you use to log in the system). Otherwise you may get errors like ‘cannot write to slapd.pid’.
