Authenticating user's join domain credentials ? --- win32 api ???

Hello Gurus,

I have a scenario where I have to validate a given set of credentials,
without actually joining a computer to a domain, using the credentials.

The information I have
username
password
domain name
computer name

I am trying to find a windows native/managed api, which would let me do that.
I did find some api which would let me Join the computer to the domain and
unjoin from the domain.
I am sure these api, internally, are using some low level functions/api to
authenticate the credentials first before attempting to join the system to
the domain.

Your answers are highly appreciated.

Thanks in Advance.
Srikanth

Many people just use an Ldap bind attempt to see if it
succeeds under the provided credentials, or if it fails
over to an unauthenticated bind.
