Missing unix user

Since I can’t access the web environment of yunohost,
I added my main user manually through sudo yunohost user add folatt.

It appears in the yunohost user list

admin@Gildurklaus:~$ sudo yunohost user info folatt
firstname: Folatt
fullname: Folatt RPG
lastname: RPG
mail: folatt@guilder-test.eu.org
mail-aliases: 
  - root@guilder-test.eu.org
  - admin@guilder-test.eu.org
  - webmaster@guilder-test.eu.org
  - postmaster@guilder-test.eu.org
mailbox-quota: 
  limit: No quota
  use: 0.0K
username: folatt

But it doesn’t appear as an unix* user.

If I remember correctly, that was not the case when I added a user via the web application.

Is this a bug?
Did I misremember?
Or did I do something wrong?


P.S.

I always get confused by terminology.
Is a user in /etc/passwd in linux called a UNIX user?
What’s the correct term for a user within Yunohost? A Yunohost user?
Is a Yunohost also an ldap user?

An user created on YunoHost isn’t an unix user, it’s an userin the ldap database.
If you need an unix user, you can create it, it will not be linked to YunoHost.
As far as I know.

I guess I must have created a unix user in the past then?
