[squid-users] Re: upgrading from 3.3.8 to 3.4.5 crashes negotiate_kerberos_auth from Markus Moeller on 2014-06-22 (squid-users)

Hi George,

You can ignore this. I try to get the group information from the
Kerberos token. And if the token is "old" as you say the Kerberos libraries
just return the error you see. I might have to change it as a Warning
instead of an ERROR message.

Thank you
Markus

That did the work Markus, thanks.

Now it doesn't crash but I still get lots of in the log files

negotiate_kerberos_auth: ERROR: krb5_pac_get_buffer: Invalid argument

It seems to happen if the token is "old". Any ideas where this comes from ?
