Well, personally I'd recommend not to use wildcard certs at all
=> I never tested anything like this.

python-ldap simply relies on OpenLDAP libs which in turn rely on 
OpenSSL. Hmm, so this should be probably raised on the openldap-software 
mailing list.

You might wanna dive into the source of ldapwhoami and look up which 
options they set. BTW: Are you sure that your local python-ldap 
installation uses the same OpenLDAP client libs like the ldapwhoami 
command-line tool?

Ciao, Michael.
