Adding support for squid to use kerberos authentication would help increase security when wanting to use Windows integrated (transparent) authentication.
Currently only LM/NTLM authentication is supported for Windows integrated (transparent) authentication.
The problem with the above is on windows vista/2008 and higher only NTLMv2 responses are supported by default
(Microsoft has disabled LM & NTLM responses to increase domain security)
currently the squid auth helper squid_kerb_auth and negotiate_kerb_auth are installed but the libraries libkrb5support.so.0 is missing, so they can not be used.
At minimum can the libraries to be able to run squid_kerb_auth and negotiate_kerb_auth be included, so it can be configured manually though ssh?
and work on adding web GUI support in the future after that.
If you're inclined to roll your own IPCop for the time being, I believe that if you comment out the following in the config/rootfiles/krb5 file, it will build what you're looking for.
#usr/lib/libkrb5support.so.0
#usr/lib/libkrb5support.so.0.1
