Re: support for wildcard certficates

[Rahul A. <ra...@sy...>]

Hi Michael,
Thanks for the response. I think you have pointed to the correct 
problem. ldapwhoami seems to be using ldap library version 2.3.30 
whereas python-ldap is probably using 2.1.30. And from this post 
http://www.openldap.org/lists/openldap-software/200504/msg00304.html it 
is evident that support for wildcart certificates has been incorporated 
in a version in between these two.

Thanks a ton for the immediate response.

Regards,
Rahul.
