[keycloak-user] Suggestions and fix for e-directory user federation provider

Hello everyone, im using e-directory federation ldap provider and came to this bug KEYCLOAK-3099 <https://issues.jboss.org/browse/KEYCLOAK-3099> as i was experiencing the same problem. e-Directory sends guid attribute as byte[] so it needs to be declared as binary the same way as its done for activeDirectory. Sending simple diff to fix this issue if you consider this as helpfull. Novell was acquired by microfocus and their product has been renamed to netIQ eDirectory so i incorporated that change as well. Another thing i noted were 2 incorrect attribute mappings in administration console. "username" -> "uid" correct as long as users are enabled for linux (not default) otherwise cn. So cn should work for more cases than uid. "firstname" -> "cn" wrong, should be "givenname" Cheers Tom
