AW: Pam configuration files



Hi guys,

concerning the "Pam configuration files" issue, I would like to ask if
there is a way to tell ssh (via different config-files) to use different
authentication methods (ie to use a special pam_service-name)

My idea is as follows:

having one box with two instances of ssh running. One instance is only
accessible from outside the firewall (with strong authentication), the
other instance is only accessible from inside the firewall (and hence
has significantly different - ie "loser" - authentication requirements).

Would that be possible without having to recompile the ssh-binary? I
want to avoid that for several reasons! (It should be possible to use
two different config-files and hence two different ports - and only one
port is allowed for external access on the firewall - with only one
binary; but is it also possible to specify the pam_service-name to use
in the ssh-config-file?)

TIA for any help you can offer.
Sascha
