After about 3 days of banging my head against the code, I finally worked
out what the issue is. So for any future people looking and getting an
error about 'Not enough memory is available to complete this request',
SEC_E_INSUFFICIENT_MEMORY then is it likely that you are sending a
Negotiate blob into a Kerberos context.

The blob I was getting from IE is a Negotiate blob, not a native Kerberos
one and so are decoded differently in ASN.1 and I guess the ASN.1
parser used by SSPI is not smart enough to work out when it is
being fed something unexpected and runs out of memory trying to 
decode what it is given. 

So make sure you are doing:

sa = sspi.ServerAuth('Negotiate')
err, sec_buffer = sa.authorize(data)

*not*

sa = sspi.ServerAuth('Kerberos')
err, sec_buffer = sa.authorize(data)

Since win32ui.pyd ( and I guess others) no longer includes vc90.CRT manifest
"import win32ui" fails from vc8 built executables. 214 and previous are working 
fine.

Thanks for the excellent software!
