Has anyone seen this error while changing OID information in Infrastructure tab of OAS? Error message: Operation failed to pass validation. Data for the Application Server instance may not have been migrated to the new Internet Directory server. Please check Admin Guide for procedures. Error connecting to Oracle Internet Directory Server specified by <SERVERNAME>:636. Connecting as Application Server instance specified by 'orclApplicationCommonName=oasinstance1.<SERVERNAME>,cn=IAS Instances, cn=IAS, cn=Products, cn=OracleContext'. Base Exception : oracle.ias.repository.schema.SchemaException: Unable to establish secure connection to Oracle Internet Directory Server ldap://<SERVERNAME>:636/ Base Exception : javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials] We have a distributed configuration with OAS on one machine and OID/SSO on another machine. The first time adding the OID information was successful without any issue but now getting the above error when we are trying to change the OID information to a new server. Is there any place on OAS server or metadatabase that it stores this information. Can we directly go and clear that information? Any tips or help is appreciated. Thanks, Sushil
