Out of curiosity, why are you happy to see this change?

Previously when using adcli to join a RHEL <7.7 system to the AD principles came out in this format: EXAMPLE$@AD.DOMAIN.COM

Now when doing a join with adcli we are getting principles in this format: example$@AD.DOMAIN.COM

Is this still a legal NETBIOS name? I mean I know it can work, it is just a string from kerbs perspective, but I was under the impression that the AD was pretty specific about what it expected the host principle to be. I am still digging into this, but so far this has broken some of our kerb code and it appears to have broken adcli update as well because it is looking for the uppercase principle while only the lower case principle is available in the keytab.

I'm very happy to see this change. This closely matches with how winbind previously would to do the joins.

I don't know the answer to your specific question, but I am happy about the change.

Apologies, the issue is we moved from using winbind via realmd which now seems to be broken due to this: https://bugzilla.samba.org/show_bug.cgi?id=14007 to using adcli, our realmd.conf file had previously lower cased the computer-name like so:

computer-name = example

And samba apparently uppercased it on the join (EXAMPLE$). adcli appears not to do that (example$). After some long research it looks like lower case is entirely legit for NETBIOS names, but for whatever reason samba chooses to upper case the names.

So the change in behavior was unexpected, but is valid. However, getting net ads join to work again in RHEL 7.7 is probably a good idea on Red Hat's part.

In short I expected adcli to act like net ads join, it doesn't, the former will accept upper or lower case and probably anything in between, the latter upper cases the name. Solution was to upper case the name with ADCLI so that it matches what we had previously. Longer term solution is to be case insensitive when looking for a principle in the keytab.
