I'd like to know if anybody knows, how to use the AUTH command on the POP3. I've been trying to read the RFC, all it provides is that the AUTH command, can follow the mechanism required to authenticate.

My university servers use Kerberos 5 to authenticate, plain text not allowed. So I need to issue :

AUTH GSSAPI

I get a + and then I have to provide a response. My question is what do I responsd with?

I guess I thought about it, and it was probably the Kerberos Ticket. So do I have to run kinit, do a klist ... and then read the Ticket information, and then send it to the POP3 server?

Thanks!

GSSAPI is only 'spoken' by system libraries and uses very cryptic strings
to transfer the kerberos tickets encoded from and to the server.
So it's near impossible to copy/paste the necessary info into a
'typing' connection.

Normally you use a GSSAPI-enabled Mail-client(MUA) to
let it do the work for you. It connects, notices that the
server speaks 'GSSAPI', enters the dialog and does
authenticate you by kerberos ticket instead of asking
for user and password.
