setting up openldap to proxy to AD on SUSE ENT 12

[N6Ghost <n6ghost@gmail.com>]

hi all,

I am trying to setup an openldap proxy to AD and i need to use SUSE 
Enterprise Linux 12.

Hostname:/etc/openldap # rpm -qa|grep -i openldap
openldap2-2.4.41-18.43.1.x86_64
openldap2-client-2.4.41-18.43.1.x86_64

what I am trying to do, is proxy an application (with 1000s of users) 
from talking directory to AD, to talking to openldap. and then have 
openldap talk to AD.
look across the net is a bunch of stuff,  but most of it does not seem 
to apply, or work.  look at the offical doc, says use sasl but you must 
have an local entry with a {sasl] tag on the user thats not really ideal 
and work make a huge problem.  a few of the posts online just said point 
to AD via ldap is possible? and this application also has a group lookup
as part of its auth process...  eg, only member of groupX can access....

any help in this would be huge.


seems, i am mixing up a few different ways of doing this whats the bets 
way to do this?

Thanks
