[Mono-devel-list] Login application

[Rafael Teixeira]

Yeah you are right, we already have many things implemented in managed
code to deal with such concerns. I think that we have some code in
place, that uses PAM to give us a "WindowsPrincipal" but I'm not sure
if the necessary plumbing in XSP/Mod_Mono is in place to use it to do
the Windows Authentication bit.

Our security guru, Sebastien Spouliot, and the XSP's creator Gonzalo,
probably have more to say. Also you can take a look at the sources to
see how class WindowsPrincipal is implemented in Mono, and the XSP
code, obviously.

Also we have classes to access LDAP repositories so you can try to
integrate with LDAP-based, or at least LDAP-compatible, mechanisms
when dealing with  authentication/ authorization.

Fun,
