We too wish to modify our /bin/login for Kerberos authentication
purposes. Various folks here at the university as well as from
Transarc Corp. have been trying to get the source from IBM in order
to modify it. Apparently the RS/6000s do not use /bin/login as most
other unix machines do. Additionally, your problems don't end there.
According to Transarc, telnetd must be modified too.
For now we are waiting patiently to get our hot little
hands on the source so that we may hack it.

I looked at the alternative authentication methods too. The big
problem I saw was that there was no way to trap the password from the
system login to use in any of the alternate authentication methods.
If anyone knows how to do this, please tell us!

The only way I know of is to arrange to obtain the source from IBM.
If you find another way, please post.
