Fix: Setting Env Var, when it is not used

Kraemii · Kraemii · commit edc1b99019c7 · 2026-03-10T15:42:55.000+01:00
When instead of the environment variable a given config path or the default is used, set the environment variable accordingly. This is necessary, as the GSSAPI does get the path via the env variable only.
