This is not a bug; it’s well known that setting username max and min to strange values will cause strange behavior.

For example, if you set max username length to 3, and your site has hundreds of users with existing usernames … you’re gonna have a bad time.

I suppose we could add clearer warnings in the help text for this setting, though.

3

Since we started the site with the 6 min and 8 max settings in place, there shouldn’t be any usernames that are shorter than 6 and longer than 8.

Are there system usernames that I am not considering that are causing this failure?

Background: Our usernames are our employee user IDs that are constrained to 6-8 characters. Since we’re not yet tied into our LDAP service, we want to help guide/limit users with respect to the username values they manually enter during sign up. Once we hook into LDAP, we won’t have this hokey edit/constraint in place.

4

Oh fair point if you started with these settings all should be well. It is changing them later that causes major trauma.

5

Search through the user table to see if any users exist with usernames outside of your allowed bounds.

6

It looks like we have compatible data, but an error still occurs.

On a site that encounters this error, several Excel macros for min and max username length report 6 and 8 respectively against the report of all users. Those are within the bounds of our min and man username settings mentioned earlier in this topic.

7

Can you rename system to systemus… or something…

min_username_length longer than 5 is a huge pain due to that…

Although I tried that, it didn’t workaround the issue. Which didn’t surprise me because system already meets the min length of 6 requirements.

Since our non-LDAP situation and therefore the impact of this issue is temporary, I homed in on using 5 and 10 for min_username_length and max_username_length respectively. At least that enables certain user settings changes to work.
