Proposed changes to configure.in for Samba 2.2.0 for PAM

[Richard Sharpe]

Hi,

Here are my proposed changes for configure.in for Samba 2.2.0.

As you can see, I check to see that the PAM libraries exist, and I respect
the setting of --without-pam.

However, things that I do not do is check to see that /etc/pam.d/samba (or
that the equivalent entries exist on Solaris or HP/UX or other PAM-aware
versions of UNIX). 

Is this needed? I have found that the file /etc/pam.d/samba was added
automagically for me by the configure script or something when I enabled PAM.
