User name email suffix stripping

All,

We've had a problem for years where people enter their email address as the user name, which fails because our current configuration assumes they're entering just their user name. We've had a JavaScript attached to our login pages for a long time which was designed to strip those suffixes off. But occasionally one would slip through anyway. I've never been clear on what set of circumstances led the JavaScript to fail, but it's been happening more frequently of late.

So over the past week we spent some time fiddling with user.txt and expressions, and came up with a server-side solution which appears to work.  Here is the code:

::Common
If login:user =~ /@.*$/i {
  Set login:user   = REReplace(/@.*$/i, "", login:user)
  Set login:loguser = login:user
}
/Common

This block of code goes immediate before the opening ::LDAP bit.  If you wish to adjust this for use on your own servers, just swap out the email suffixes that you want to strip off in that regular expression on lines 2 and 3.

The advantage of doing it server side in user.txt is consistency. No worrying about different browsers or the rare unicorn people who have JavaScript turned off or anything.

We've had this going for a week at this point with no issues.

Hope this helps someone.
