Hi.  IN general if there isn't a reason for confidentiality, please at
least copy the krbdev list on interactions with us.  You may get a
faster response if the member of the team you contact is busy and
you'll make it easier for us to have better internal communication.

That's really great to hear.

We are still very much interested in this code.  However you should be
aware that we've reached a point in the 1.3 release cycle where we
would not feel comfortable accepting the code for 1.3.  We are still
accepting some new features, but mostly from people with commit access
and only when the feature is well contained.

A new RPC implementation does not meet this constraint; if the new RPC
library fails or runs into build problems, it makes our release

mSo we will probably not commit the code until after the 1.3

Configuring our CVS head on Solaris with Autoconf 2.53 works fine for

Also, one issue we'll definitely want to be sure of before accepting
the code is that all the symbols are renamed so that the RPC library
does not shadow the operating system RPC library.  If that happens,
then NIS and other NSS-based RPC services can fail.  Arguably the OS
should be binding against versioned symbols or otherwise making sure
that it uses the right RPC library, but in practice this tends not to
