To address this issue reset the ADS Endpoint ID's password.
Please run the following etautil command to re-enter the password used by the ID that acquired the ADS endpoint (or re-enter the password via the UI). The USER/PWD would be the credentials used to log into the Provisioning Manager and Password would be the password used by the ID that acquired the ADS endpoint.
etautil -u <imps user> -p <imps user password> update 'eTNamespaceName=ActiveDirectory' eTADSDirectory eTADSDirectoryName='<ads endpoint>' eTADSAuthPwd='<password>'
etautil -u etaadmin -p [email protected] update 'eTNamespaceName=ActiveDirectory' eTADSDirectory eTADSDirectoryName='Tom_ActiveDirectory' eTADSAuthPwd='[email protected]!"'
