Re: saslauthd & PAM??

Off the top of my head and i'm not sure this is the same bug, you might try I think it is the flag -n1 or -n0, you may need to limit the number of threads for the process to 1.


If that doesn't work and upgrading does, file a bug with on the fedora bugtracker so they fix it in the distribution.

It was worth a shot but I just checked, my version of saslauthd was not
compiled to use sasldb as an authentication method:

# /usr/sbin/saslauthd -v
saslauthd 2.1.23
authentication mechanisms: getpwent kerberos5 pam rimap shadow ldap



Perhaps try sasldblistusers2 to check your user database?

What I have been able to figure out so far is that the parameters are
being passed to saslautd (eg testsaslauthd -u username -p password -s
smtp) but saslauthd appears to simply sit on the request, running a
-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

I think this means that testsaslauthd is passing the query to saslauthd
correctlybut saslauthd for whatever reason isn't contacting PAM




auth		include		password-auth
account		include		password-auth

selinux is disabled

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

Thanks, Jeff

It looks like the supplied version of saslauthd on Fedora 16 is simply broken, a recompile with 2.1.25 worked with no issues.

Thanks, Jeff
