Re: some thoughts about RDN
The software I try to use is Roundcube webmail, i log to it to read email
using full email address and password. It provides backend for ldap
addressbook so and can provide for ldap binding full email or only username
(part before @) and password from email logging.
As I'm new to LDAP at all so I don't know how to create login DN for this
to use email attribute of users to authenticate. I cannot tell you if this
software architecture is invalid because I have too little knowledge in
Anyway thank you for your comments.
