Hi Kevin,

Did you try Russ' suggestion of '"ckpasswd" without the "-s" option?
It would permit to remove the setgid bit you set.

See the EXAMPLES section in to see how 
PAM can be configured.

Oh, I also see that the readers.conf example file shipped with INN does 
not contain any example of ckpasswd use...

So, I suggest to:
- improve the basic readers.conf example file to add an example of 
"ckpasswd" (PAM) and "ckpasswd -f" (file) uses;
- change the examples in the readers.conf man page to use "ckpasswd" 
instead of "ckpasswd -s" (and just say in a sentence the difference);
- change the examples in the readers.conf man page to use "ckpasswd -f" 
instead of "ckpasswd -d" (using a plain file is far more easier);
- add a "QUICK START" section near the beginning of the readers.conf man 
page to just document these two most frequent uses.

Do you see any other way to improve that documentation?
