Debian Package problems

Does anybody know what's going on with the Debian 7.1 RC4 packages? It
will not let me create any users or even talk to the backend.
If I try to create a user (as user postgres), it asks me for a
password, but it's not the UNIX password because I tried that (I changed
the password right after I installed the packages).
If I try to connect through psql, it asks me for the password again.
It looks like it's using password auth instead of ident auth, which used
to be the default.
There's nothing pointed in the packages web pages, a caveat or
anything. I've looked.

Thanks,

-Roberto
