>Description:
The Kerberos 5 PAM module (src/lib/libpam/modules/pam_krb5/pam_krb5.c)
ignores the no_ccache option and always saves the credentials in a file.

>How-To-Repeat:
For example, configure ports/mail/imap-uw to authenticate with Kerberos.
In /etc/pam.d/imap, put:
    auth    required   pam_nologin.so    no_warn
    auth    required   pam_krb5.so       no_warn try_first_pass no_ccache
Contrary to the pam_krb5(8) man page, a credentials cache will be saved
in /tmp/krb5cc_%d.

>Fix:
I'm not familiar enough with PAM and Kerberos to provide a fix.  :(
Maybe in my "spare time"...
