Thank you Scott. The problem I'm finding is when I try to use at the 
same time mod_shib and mod_auth_gssapi.

mod_shib is linked to libshibsp-lite.so, whereas mod_auth_gssapi 
dynamically loads mech_eap.so which is linked with libshibsp.so.

Apache uses RTLD_GLOBAL to load the modules, which means that if the 
symbol names are the same, problems might arise. Curiously it does not 
seem to fail in Centos7, but in Debian 8 it fails. I'm still debugging.

I was wondering if I could solve my problems by linking moonshot with 
libshibsp-lite.so instead. I understand that would require having an 
instance of shibd running.

Best regards,
