Hi to all, for my companty I'm triing to setup a LDAP proxy to our Active Direcory implementation, after some time I have found several problems on some critical application that does not support multiple OU anche CN formed by "Surname Name" caused by the bad structure and nomenclature on the AD, but we cant change it. To work around the problem I have used the rwm module to rewrite the client binddn query part to AD format name.surname@domain, but the proxy return:

So there is a way (or a better way) to accomplish this need? Best regards, Giuseppe.
