The reasons for locking a users

What are the reasons for locking users?
They sometimes have to be manually unlocked.

Pydio Cells Home Edition
Centos 7
HDD 50 GB (3 GB used)
Processor - 2 Cores
9 users

Hello @Sophist,

This means that the user might have tried to connect, with many attempts in a short period with the wrong credentials.

It’s actually a hard coded limit of 10 failed login attempts after the last succeeded one (without the time factor).

Thank you for this information.
I assumed that the locks occur because the user is using too much server computing resources.
