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)?

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
