[STR New]

When authentication is enabled in cupsd.conf, and there is a Listen
directive with a path to socket (Listen /var/run/cups/cups.sock), it fails
with Broken Pipe error when setting printer's default options.

In the logs one sees 
cupsdAuthorize: Authorization=""
cupsdAuthorize: No authentication data provided.

Removing Listen /path/to/sock directive workarounds the problem. 

cupsd.conf and error_log are attached.
