Re: Support for multiple GSS libs

Ah. But you still need the ability to select the mech at runtime -- by
that point only dlopen()/dlsym() at the app level or mechglue in the GSS
libs will help.

Q: Why prohibit the use of SPNEGO in SSH? Are there archives where the
   issue was discussed that I can read?

   Is it because, if GSS is selected, but the GSS mech negotiated by
   SPNEGO is not accpetable, then there is no way to go back and
   re-negotiate at the SSH level? Is there no way to go back and
   re-negotiate at the SSH level?
