Yes. I have that account: nslcd-user. I can create a keytab for
nslcd-user. let's say nslcd-user.keytab. Now, what is the sytax of the
line to add to nslcd.conf? There seems to be no way to specify that.

OK. If I have understood this correctly, for me my server, ip=
192.168.1.3 has fqdn hh3.site so I should specify
uri hh3.site rather than uri 127.0.0.1 or 192.168.1.3 no?

That's what I don't know how to do!
