USERS | I cannot add users with no apparent reason. Maybe the name?

Hi Boris,
I have just sent you the logs. Here’s the description of the problem:

I can add new user with totally random username, name, surname.
I cannot do the same with many other usernames that I choose. Being that I cannot find a pattern in this behaviour, I have sent you the logs. Could you kindly tell me what’s wrong with some user names? I don’t use special chr’s or spaces…
Thanks a lot

Simone

Are you using Users app (will be decommissioned soon) or platform users page (the new simpler UI)?

OPS…the oldest one. Let me try the new one I was not aware of. Thank you

SB

It must be non lower case usernames, we cannot allow mixed case.
Also I think we have that check missing on the new UI, but I will have to add it, otherwise even more problems will start to happen later

ouch…I have just created: lower case names and mixed cases names.
Apart from that it works great. I have already removed the legacy app.
Thx

SB
