Older Shibd version on Debian: mod_shib undefined symbol

[Wessel, Keith]

Hi, all,

I'll start by saying that I know Debian isn't officially supported for the SP and that one shouldn't run outdated versions of the software. We've got a customer that's stuck with Debian, though, and will be updating soon but for now is on Debian 11 which contains SP 3.2.2.

With all that said, I'm wondering if anyone's run into this before. When trying to load the Apache module, we're getting:

Cannot load /usr/lib/apache2/modules/mod_shib.so into server: /usr/lib/x86_64-linux-gnu/libshibsp-lite.so.10: undefined symbol: gss_export_name_composite, version gssapi_krb5_2_MIT

I've looked at all of the usual suspected missing dependency packages like krb5-user and libgssapi-krb5-2, and they're there.

Has anyone seen this, or does anyone have any suggestions beyond upgrading the server or, better yet, choosing a different (RPM-based) distro?

Keith
