Hello,

  being in the process of upgrading from pgadmin3 (and taking the
opportunity to move the new pgadmin4 onto a proper app-server), I
found this article, written some 2 years ago, being the only resource
I could find all over the Internet, which, in a sensible way,
describes the task of logging into the postgres server, in the case
when this happens to be purely Kerberos5-driven.

I couldn't find any mentioning of this task in the pgadmin4
documentation. :(

So, since this quoted article is from quite a time back, may I kindly
ask for an update on the status of this matter, how it may have
proceeded in the meantime and what is currently considered best
practices in such a case of pure Krb5 operations? 

thanks and best regards,
PMc
