I rebuild mit kfw 4.1 with the latest code (
https://github.com/krb5/krb5/commit/0415c857d320347bbd7ab33bde677b977387d940,
commit 0415c85) and I can renew kerberos tickets inside FILE credential
cache on mit kfw 4.1.
I uploaded msi installer on
https://github.com/eubnara/krb5/releases/tag/20251030 release.
I suggest that mit kfw 4.1 official version should also be updated with the
latest krb5 codes on https://web.mit.edu/kerberos/dist/.

cf.

In the MIT KfW build based on commit 0415c85, if a ticket is already
issued, clicking the *"Get Ticket"* button fails to obtain a new one. You
need to either *"Destroy Ticket"* first and then *"Get Ticket"* again, or
use *"Renew Ticket"* instead.
In the official mit kfw 4.1, clicking *"Get Ticket"* would overwrite the
existing ticket even if one was already issued.
I suspect that PR #218 <https://github.com/krb5/krb5/pull/218> might have
influenced this behavior, but I haven’t fully confirmed it yet.
