The pam module is only used for console and xdm login isn't it? So
the console login ends up in the default uid pag. Then we have an
"afslog" in the login scripts so that we can get away with a pam
module that only knows about kerberos.

All sites I know have list (but not neccessarily read) on $HOME.
Then $HOME/Public is "rl" and $HOME/.bashrc -> $HOME/Public/.bashrc.
Sorry if this is not the answer you wanted to hear ;-)
Remote logins (telnetd, rshd, ...) per default create a new pag for

I think this is "as designed". To get a new pag in a xterm you need a
new shell in a new pag. "pagsh" gives you a new pag and sets a

I don't think this has been implemented, do you want something like
pagsh sh -c "kinit $* && $SHELL"
