What were you trying to do that didn't work?

When testing new cepces against Win 2025 I was trying certificate auto-enrollment against AD CA using command: samba-gpupdate --force --target=Computer

What is the impact of this issue to you?

Certificate enrollment crashes even before requesting or renewing certificate.

Please provide the package NVR for which the bug is seen:

cepces-0.3.12-1.el9

python3-cepces-0.3.12-1.el9

How reproducible is this bug?:

Always

Coment:

Got TypeError in auth.py  file. _init_ccache method crashes because the gssapi library expects the keytab type bytes, but it is passed a str.

Error: TypeError: expected bytes, str found in gssapi/raw/ext_cred_store.pyx

For the purpose of the test I changed one line in file: /usr/lib/python3.9/site-packages/cepces/soap/auth.py

From this: store =
