Package: wnpp Severity: wishlistmod-auth-kerb is a terrific Apache module to authenticate connections using Kerberos; it even supports GSSAPI negotiation (SPNEGO) - ie. single sign on authentication using Apache2 & Kerberos!
I repackaged mod-auth-kerb for Apache2 & added some more documentation: http://cgi.sfu.ca/~jdbates/moin/moin.cgi/KerberosApacheModule
