For the basics, see http://support.microsoft.com/support/kb/articles/Q102/7/16.asp ('User Authentication with Windows NT'). The details are described in http://msdn.microsoft.com/library/psdk/logauth/lsaauth_6e5q.htm ('Using LSA from a Logon Application'). You'll have to create an authenticaton package like discussed in http://msdn.microsoft.com/library/psdk/logauth/lsaauth_6cs3.htm ('Windows NT?Style Authentication Packages').

As a starting point, use http://msdn.microsoft.com/library/psdk/logauth/lsaauthpp_1rxh.htm ('LSA Authentication')

Thanks, but I already read all these articles and I still have a lot of questions, for example - how to calculate user's response. My target is to logon via Lsa using existing authentication package - ntlm.

Thank you for help

Well, in this case you could simply call 'LogonUser()'

Well, if you thought it'd be better to delete this one, you should just have left an explanation - that's why I asked...
