i have seen it in /home/e-smith/db/accounts.
If you still see pseudonyms in the accounts database that appear like the following
(for users like first last):
first_last
first.last
Then you need to delete all those entries.
Yes 790 of them, so maybe you need to write a script to do so.
Once deleted you can run the post upgrade & reboot events, which should recreate all the pseudonym variants.
If
first_last
first.last
are definitely not in the accounts database, then something else is wrong & I do not know what.
