I face this error during timldap start process , till now I have no resolution for this why this error occur in my environment , Same I completed some steps as suggested by IBM such as latest gskit But not resolved So finally what I did ,I had recreated itimldap instance.

1 ) Reach to path : -

/opt/ibm/ldap/V6.3/sbin

2) Execute below command

./idsidrop -I itimldap  –r

3) again create itimldap instance from ITIM middle ware utility

java -jar  cfg_itim_mw.jar
