r6028: A MAJOR update to intergrate the new credentails system fully with GENSEC, and to pull SCHANNEL into GENSEC, by making it less 'special'. GENSEC now no longer has it's own handling of 'set username' etc, instead it uses cli_credentials calls. In order to link the credentails code right though Samba, a lot of interfaces have changed to remove 'username, domain, password' arguments, and these have been replaced with a single 'struct cli_credentials'. In the session setup code, a new parameter 'workgroup' contains the client/server current workgroup, which seems unrelated to the authentication exchange (it was being filled in from the auth info). This allows in particular kerberos to only call back for passwords when it actually needs to perform the kinit. The kerberos code has been modified not to use the SPNEGO provided 'principal name' (in the mechListMIC), but to instead use the name the host was connected to as. This better matches Microsoft behaviour, is more secure and allows better use of standard kerberos functions. To achieve this, I made changes to our socket code so that the hostname (before name resolution) is now recorded on the socket. In schannel, most of the code from librpc/rpc/dcerpc_schannel.c is now in libcli/auth/schannel.c, and it looks much more like a standard GENSEC module. The actual sign/seal code moved to libcli/auth/schannel_sign.c in a previous commit. The schannel credentails structure is now merged with the rest of the credentails, as many of the values (username, workstation, domain) where already present there. This makes handling this in a generic manner much easier, as there is no longer a custom entry-point. The auth_domain module continues to be developed, but is now just as functional as auth_winbind. The changes here are consequential to the schannel changes. The only removed function at this point is the RPC-LOGIN test (simulating the load of a WinXP login), which needs much more work to clean it up (it contains copies of too much code from all over the torture suite, and I havn't been able to penetrate its 'structure').
