Both of these releases are LDAPv3 implementations, allowing
an LDAPv2 bind (for Umich LDAP compatibility).

This filter, aside from being malformed (missing outer parens),
should always evaluate to Undefined (and hence treated as False)
as uniqueMember doesn't have a substrings matching rule.
Also note that as a NameAndOptionalUID (or DN) values are not
character string s(in the abstract), substrings matching
is nonsensical.  In LDAPv3/X.500, component matching should
be used instead (which will be supported in OpenLDAP 2.3).

That's a known bug in the old release.

This refers to the LDIF version, not to the LDAP version.
Publishing version 2 here was considered a bug.

We fixed the bug.

Your assumptions.  The later releases are correct here.

Lastly I note that 2.1 and earlier releases are considered
historic.
