Hi All,

I want to use my AD for Linux authentication, I checked the option of using
LDAP over SSL, and sow that I can run from My Linux machine "getent passwd"
and get my users list including their password hash.

How can I block this? (and still give my Linux machines the ability to
authenticate using SLDAP)

P.S

I also checked the option to use AD NIS abilities and have the same issue
using "ypcat passwd"

Thanks In Advanced!
