LDAP email mapping

So I have the module up and running, its authenticating users just fine, importing info from the LDAP directory, and mapping the email from LDAP to the field in the drupal profile. My problem is that I am in a situation (University) where the LDAP directory cannot be edited at all so I would like to get it where it imports the username (already happening) email, and doesnt have an option for password since I'll never be using the drupal database for authentication. Right now when you view the profile, the email is there in the field but when you try to submit it it says that the email is already taken. I'm assuming this is because its trying to go back out and update the email in the LDAP directory which it cant and I dont want it to do. I dont know if the module has this capability but I think it would be extremely useful if it does.
