This is required for backwards compatibility when installing the -full
or -full-dbg package variant: PAM is enabled now but no configuration
present, so all login attempts would be denied ...
Creating /etc/pam.d/ngircd including "auth required pam_permit.so"
restores the old behaviour of allowing all connections.
In addition to the "ngircd" and "ngircd-full" packages a new package named
"ngircd-full-dbg" is build: this package contains all the features of the
"full" package but includes debug code and both the --debug and --sniffer
options and the resulting binaries are _not_ stripped.
