Hi, this is my first post to the list, I'm not a member, please cc me directly. I'm converting from courier imap, and want to bring a special problem to your attention: I would like to use auth_bind and prefetch, b/c due to data security restriction the user information is only visible to the user himself. From http://wiki.dovecot.org/AuthDatabase/LDAP I found out that pass_attrs only works if no userdn template is set. But when unsetting userdn, dovecot-auth still tries to find the information from pass_attrs before binding. I'm no coding expert so here is my question: would it be possible to make pass_attrs work with userdn? If yes, even prefetch would work. right now, when using userdn, pass_attrs is ignored, but also userdb and user_attrs is impossible for me, because it is done anonymously, it can't reuse the bind from passdb, and can't construct a bind as passdb could. for now I defined a dummy user in ldap, but that's not the ideal solution, since then this dummy user has access to all usernames, uids, uidNumbers and gidNumbers. thank you for your attention best regards matthias subik ps: is there a list of all keywords and parameters?
