i installed mailman3-full on debian 10.
During installation, it asks me to enter the admin user credentials.
After configuration, I restart mailman3 and mailman3-web.
When I try to log in for the first time by entering the admin credentials, a message warns me that the credentials are incorrect.
I looked at the mailman logs, but I find nothing.
It seems that it is a django authentication problem, because even in the django admin panel I can't log in.
Looking at the mailman3web db, in the auth_user table, I see the admin user.
How can I see why it does not accept the credentials?
Thank you in advance
