[with patch, needs work] Kerberos authentification for SAGE notebook

[kkilger]

This patch adds Kerberos authentification support for the SAGE notebook. It also adds the options krb_srv, krb_realm for the notebook() command.

This patch however depends on pykerberos which depends on kerberos which depends on a couple of other libraries all in all a little less size than SAGE itself and all not in SAGE :-). Nevertheless ...

Greetings, Kilian.

This doesn't apply in sage-3.2.alpha1

Kerberos shouldn't be required to use the notebook. Make Kerberos authentication optional.

my.patch is replaced by sage-3950_1.patch and applies in sage-3.2.alpha1

[TimothyClemans]

OK now Kerberos isn't required.

Hi,

I like the design of this patch and how the kerberos stuff is optional.

Unfortunately, this is hard to referee if you don't explain to me how to install pykerberos. Also, the patch itself should contain code that says "hey, you need kerberos, and here's how to install it" when the user turns on kerberos via an option to notebook, but

import kerberos

fails. That could be either a paragraph of text, an optional spkg to install, or a link to a wiki page that describes what to do.

OK?

Thanks!

notebook is deprecated, so this can probably be closed

Yes.
