LDAP OU shows invalid bind credentials, but LDAP server connection test is successfulIssue When running a test connection from the LDAP server, the test connection returns successfully. Running a test connection on the OU, running an import, or checking the LDAP listener status, though, all return error: LDAP: error code 1 - 000004DC: LdapErr: DSID-0C090A4C, comment: In order to perform this operation a successful bind must be completed on the connection., data0, v3839ReleaseAny ServiceNow release. The underlying issue is on the LDAP configuration Active Directory LDAP servers.CauseThe test connection on the LDAP server level does not perform the "simple bind" operation, so if there is an issue with the user authentication through simple bind, test connection will return successfully on the LDAP server level, but anything that would retrieve data (OU level, listener, import) will fail on the simple bind operation to the LDAP server.ResolutionThere have been two issues found that might cause this error: A typo in the password field in the LDAP server record, used for login/bind to the LDAP server. To fix, reenter the known good password in the LDAP server record.Simple bind is not active on the Active Directory server (see LDAP Simple Bind failing ) and has to be reactivated by adding the pwdssp.dll to the SecurityProviders key in the registry for the AD domain controller as described in the Microsoft Technet article. Connecting from an LDAP client using a simple bind will also help determine if the issue is #1 or #2.
