Hi, I have a question; The following two commands will not work without the -Y option; ldapsearch -I -Y cram-md5 ldapadd -Y cram-md5 -U manager -f init.ldif I thought that "ldapsearch -I" will automatically choose the available authentication mechainsm? .. is this a misconception of mine ? .. or do I have something incorrectly configured ? thanks. Kind Regards, Lucio Jankok
