[SOLVED] Error after Debian Trixie installation

Hello

, I'm posting more for information than for an immediate solution!

After upgrading to Debian 13, I'm encountering errors in the nginx configuration, specifically with the "auth_gss*" directives:
unknown directive auth_gss,
unknown directive "auth_gss_allow_basic_fallback",
auth_gss_keytab,
unknown directive auth_gss_format_full.

Commenting them out works, but that's not the intended solution. ;-)

Hello,

actually, debian13 added the "nginx-mod-http-auth-spnego" package to its repository, which we previously provided.

The problem is that this package is an older version than the one we were offering.

Therefore, the simplest solution is indeed to temporarily disable Kerberos on WAPT (before migration) via Postconf.

- Uninstall the "nginx-mod-http-auth-spnego" package.

- Perform the migration to Trixie.

- Reinstall the nginx-mod-http-auth-spnego package and restart Postconf to re-enable Kerberos.

Thanks for the feedback.

Apparently, the nginx-mod-http-auth-spnegon package is not available.

NB: My mistake, the package is libnginx-mod-http-auth-spnego :P
