The mailing list for listmasters using Sympa

[Chris Spencer <address@concealed>]

We use LDAP authentication with sympa.  We also allow users to create 
accounts based on email addresses.

We do not want LDAP users to be allowed to create two accounts for the 
LDAP email (one ldap and one email) with seperate passwords....

Does anyone know how to disable account creation on users where the 
email address matches an LDAP account?

Thanks!
