I have CallManager 4.2(3) integrated with Active Directory. When logging onto EM with an old pin the message authentication error appears. When the pin is changed via CCMAdmin and logging onto EM the message error 23 is seen. Error 23 implies the userid does not exist, clearly this is wrong as it does. When the old pin is re-tried I still see the authentication error message. It appears that it may be trying to authenticate in two different places. I have checked the registry on CallManager for the directory and this is set to true. EM was working previously. I have tried new accounts and resetting TomCat but to no avail. Any assistance would be gladly appreciated.
