Nope.
Isn't possible to use gssapi authentication within the Pam accounting process
?

Mmmmh, some of the packets just debuilded don't need to be (anymore?).
I just used libsasl-gssapi-mit and had no need to apt-get source and change
the rules.
This has avoided me the fact that when compiling sasl and openldap i had
conflict with the berkeley db (sasl asked for 2.0 and openldap for 4.0 ...).
Plus some other little things. I'll give you all my comments about it when
i'll have this version working. For the moment, strikes in Paris kepts me at
home ;)

Yep, everything works fine, except that i have no TLS compiled (will do it in
the future, but for this first step, i want to use as much already existing
debian packets as possible).

Ok, seeing the four in your doc disapointed me a little ;)

It rocks ! Perhaps users would be disapointed if i change it, but nevermind
