Hija, after starting 6.4 I couldn't login, and instead was shown a bunch of those:
The domain name kerberos.realm.nr42 is not valid. It is not within a valid top-level domain. I found that this get checked in the "email_validator": # All publicly deliverable addresses have domain named with at least # one period. We also know that all TLDs end with a letter. Very well so, but this does not necessarily hold true for Kerberos REALMs. This is how we get there: ./pgadmin/tools/user_management/__init__.py:115 ./pgadmin/utils/validation_utils.py:17 It seems this was not present in 4.30, but then it also probably happens on first start only? cheerio, PMc
