How to expand sugarcrm username to be >25 characters?

[redminer]

Currently sugarcrm username could not be more than 25 characters. I use CAS SSO integration and the username is the email address, which might be more than 25 characters.

Then I need to expand the limitation from 25 to 255. How to?

I know I could create custom/Extension/modules/Tasks/Ext/Vardefs/custom.php file, but what's inside? e.g., $dictionary['Task']['fields']['name']['len'] = '255';

Hi redminer

The script is custom/Extension/modules/Users/Ext/Vardefs/custom.php
And the content is

 <?PHP
$dictionary['User']['fields']['user_name']['len'] = '255';
?>  

You also must update the script modules/Users/EditView.tpl in order to increase the attributes size and maxlength.

Cheers
