I just upgraded my system to F16 and SMTP authentication is no longer working. 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 there. 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 read(7, I think this means that exim is passing the query to saslauthd correctly but saslauthd for whatever reason isn't contacting PAM properly. sysconfig/saslauthd: SOCKETDIR=/var/run/saslauthd MECH=pam FLAGS= /etc/pam.d/exim: #%PAM-1.0 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.
