When generating/mapping operator-id records it expects the property values of org ,div, and unit. Please go through this activity LDAPVerifyCredentials in class Code-Security. This activity looks for the operator in PRPC, if not found it creates one using the Model operator specified in the Organization Unit.
In case you don't have any model operator then you might need to make use of the ApplicationProfileSetUp Activity to do create initial profile of the operator.
Thanks for the response. Unfortunately our company's ldap tree does not have or pass org,div and unit hence I could not map that those property values, If i hard code org,div and unit LDAPVerifyCredentials activity, operator page gets created. thanks.. I assume that's only way out
