Hello, I have such RDN cn=user1,dc=example,dc=com but my webmail software knows users only by emails (which is attribute to cn=user1,dc=example,dc=com) My question is how can i authenticate in LDAP using provided email? I tried sth like mail=test@example.com,dc=example,dc=com but ldap refuses such login. Thanks in advance for help Greets Pawel
