I have read the documentation afterwards, and seems that the documentation doesn't mention refint overlay works only if rootdn is configured. I would like to ask if it is (undocumented) requirement or a software bug?
I've filed a documentation ITS for this issue: <http://www.openldap.org/its/index.cgi/?findid=6364> --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration
