[Samba] ldap owncloud and samba ad

[Micha Ballmann]

Hello,

im authenticating my Owncloud aigainst one of my three domain controller 
and add a second one of it as failover. The authentication works pretty 
well. When im trying to share files or folders i have the problem, that 
it takes a lot of time until i get the username i want to share. 
Compared to my open ldap the samba4 ad needs about 10-15 seconds more to 
find a result, thats pretty stressful if you want to share for  serveral 
users.

I hope you can help me to speed up :-D.

Best regards,

Micha
