downloaded the latest openSUSE from opensuse,org 10.1 from recollection.
Downloaded the openSUSE version of Zimbra.
Go to install it, get warning, UNKNOWN version, and it states that the Zimbra I have is for SUSE 10 ???
Its installing as I speak, so I will see if I get the same LDAP error 256 from recollection that I had before.
