Bugzilla Bug 27690

If my memory serves, the default authentication method for saslauthd after the 
emerge of sasl-2.1.14 is pam, in /etc/conf.d/saslauthd:

SASL_AUTHMECH=pam

But pam does not allow saslauthd to authenticate. This showed up when using 
postfix to authenticate smtp connections. The solution is to add a file 
called 'saslauthd' in /etc/pam.d. Here's the one I used that works:

auth       required     pam_nologin.so
auth       required     pam_stack.so service=system-auth
account    required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth


Reproducible: Always
Steps to Reproduce:
1. emerge cyrus-sasl
2. Configure postfix to use sasl for authentication
3. In /etc/sasl2/smtpd.conf use "pwcheck_method: saslauthd"
4. In /etc/conf.d/saslauthd use SASL_AUTHMECH=pam

Actual Results:  
Authenticating smtp connections to postfix doesn't work

Expected Results:  
Should have authenticated

in cvs.  thanks!
