Incompatibilities between 2.1 ldapsearch and 2.3 servers?
I thought that the "ldapsearch" binary from any given release should work
with a server running a different release, but this does not appear to be
the case. Our 2.3.24 Linux servers cannot be searched with a 2.1.25
ldapsearch binary if there are a lot of results. What we get is:
ldap_result: Can't contact LDAP server (81)
If I use a 2.3 series ldapsearch binary, the search completes without
problem. The ldap server seems to think that the 2.1 binary issued an
UNBIND request:
