I use saslauthd for authentication which then uses pam. Is there a way
to get rid of auth_unix ?
sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN

This patch breaks imapd and possibly mupdate ( I cant test it )
# telnet localhost 143
* OK ..... server ready
1 login
1 BAD Missing required argument to Login
2 login cyrus dsdsdsd

3 login cyrus abc123
Connection closed by foreign host.
on what would be a successfull login, imapd exits with SIGSEGV
backtrace attached.
