I have just read about pam_listfile and it sounds very promissing.
I have created a file /etc/pam.d/telnet with the line:
   account required /lib/security/pam_listfile.so file=/etc/telnet.acl item=user sense=allow onerr=fail
and a file /etc/telnet.acl with the name og the user who should be allowed to use telnet.

But it doesen't work :-(

Is it the wrong configuration file? Or ist the configuration wrong?
Or is Fedoras in.telnetd not using pam?
ldd /usr/sbin/in.telnetd dosen't say anything about being linkt
to pam.
Any more ideas?
Thanks in advanced,
Harald
