Most installed ldap servers (ldapd's) are based on the 3.0 release of the
U-M LDAP code. Unfortunately, some of the encodings were incorrect in that
version, and because of that newer LDAP clients can not bind to older
servers. The converse does work: that 3.1 server will talk to any client
based upon any version of the U-M LDAP libraries.
I ***strongly*** encourage everyone to upgrade to the ldapd contained in
our 3.1 release, available using this URL:
ftp://terminator.rs.itd.umich.edu/ldap/ldap-3.1.tar.Z
