saslauthd, PAM & EXIM - F16

I just upgraded my system to F16 and SMTP authentication is no longer

What I have been able to figure out so far is EXIM is passing the
authentication request to saslauthd but saslauthd appears to simply sit on
the request, running a strace -f -p xxxx on the saslauthd process I can
see my username and password sitting there but that's it, its just sitting

output from strace:
fcntl(6, F_SETLKW, {type=F_WRLCK, whence=SEEK_SET, start=0,
len=1}{sa_family=AF_FILE, NULL}, [2]) = 7
fcntl(6, F_SETLKW, {type=F_UNLCK, whence=SEEK_SET, start=0, len=1}) = 0
) = 0
accept(5, read(7, "\0\4", 2)                      = 2
read(7, "username", 4)                  = 4
read(7, "\0\6", 2)                      = 2
read(7, "passwd", 6)                    = 6
read(7, "\0\4", 2)                      = 2
read(7, "smtp", 4)                      = 4
read(7, "\0\0", 2)                      = 2

I think this means that exim is passing the query to saslauthd correctly
but saslauthd for whatever reason isn't contacting PAM properly.




auth		include		password-auth
account		include		password-auth

selinux is disabled

I know I'm missing something pretty simple but not sure where to look,
suggestions would be appreciated.

Thanks, Jeff
