Greetings, I was trying to build source build postgres 8.1.x with MIT Kerberos 5 1.4.x implementation. The whole thing bombs out. After some digging, I had to hack the autoconf script (configure.in) to properly account for the way the libraries are built for 1.4.x. I don't know whether an earlier post had the same issue. I think it boils down to adding the 'libkrb5support' when all the krb5 libs are checked in the configure script. On another note, is the kerberos authentication secure, I had searched some old threads, where it was indicated the principal is not checked by the db as a valid user. Is this still the case? Thanks a lot. Mohan
