Is the software provided by Cognos? or suggesting to use a 3rd party software?
Cognos uses external providers for authentication - the setting and maintenance of user passwords is done outside of Cognos. As a Cognos Product Manager once told me... "It's S.E.P." It turns out he meant Someone Else's Problem :)
