Hi,

The default NTLM buffer length, as defined in tds/sspi.c (NTLMBUF_LEN = 4096)
is insufficient in my environment. The token returned is 7566 bytes long. As
a result, the call to InitializeSecurityContext() in tds_sspi_get_auth()
returns SEC_E_INSUFFICIENT_MEMORY.

I have recompiled with a larger buffer size (16384) and tds_sspi_get_auth()
now works.

I wonder if this is the right way to fix this - should people adjust the
buffer length as needed and rebuild? Or should the default be increased in
the trunk?

Thanks,
Sam
