[rt-users] user gets two accounts when logging in from Web and via email

[Steven McDonald]

Hi

    At our site we use sendmail with the long name feature enabled. This 
means a user that has a username jdoe and a gecos field set to the users 
full name say John Doe can have email addressed to either jdoe at org.com 
or john.doe at org.com.We also have the LDAP Overlap installed. The problem 
is the following,

When a user  logs on from the web interface their account gets 
automatically created based on their LDAP username and email, where the 
email  from the LDAP is their username at org.com. The problem is if this 
same user sends an email to RT but they have configured their mail 
client to use their return email address as john.doe at org.com as new user 
gets created called john.doe at org.com, now the user has two accounts one 
by their username created when they login via the WEB UI and the other 
when they send email directly to RT.

How can I avoid this?

Do I have to customize my LoadORCreateByEmail in User_Overlay.pm or is 
there another way.

Thanks
Steve
