On Linux, we use krb5-auth-dialog with its aklog plugin. Krb5-auth-dialog auto renews tickets and tokens, which is really nice (no need to run a separate krenew). On Mac (and replaced with krb5-auth-dialog for Linux), we use my now quite old AFSTokens application as an all-in-one app. Like I said,

2014-07-31 Thread Andrew Deason
Hi all, I've had a few users and administrators complain to me from time to time about the existence of 'aklog'. (By 'aklog' I really mean any mechanism to convert krb5 tickets to AFS tokens, but I'm referring to them all as 'aklog' for simplicity.) The need for an AFS-specific authentication step
