Receiving an error DirectAdmin: is not a valid username? We can help you with fixing this restore error.

Today, let’s see how to fix this invalid username error message in DirectAdmin.
How we fix DirectAdmin: is not a valid username error
Now let’s take a look at how our Support Engineers resolve this error message.
Recently, we were migrating the accounts from one DirectAdmin server to another DirectAdmin server. When we tried to restore some DirectAdmin accounts on the new server, this error occurred. Most of the accounts were restored successfully. But some returned this error:
user1 is not a valid username user2 is not a valid username
The reason for this error to occur is the default setting that is set for the username length. By default, in DirectAdmin configuration max_username_length is set to 10. So if the username of an account is having more than 10 characters then this error appears.
Thus, in order to resolve this error, we need to change the value of this setting.
For that, we need to edit the DirectAdmin configuration and set the value of max_username_length to a higher value. The path of the configuration file is /usr/local/directadmin/conf/directadmin.conf.
So we edit it by running the below command.
[root@server ~]# vi /usr/local/directadmin/conf/directadmin.conf
Next, we find ‘max_username_length’ and edit it as below.
Then we save the file and exit the editor.
After that, we run the below command to restart DirectAdmin.
/sbin/service directadmin restart
This resolved the error instantly.
