[Samba] shared drives are getting disconnected after some time

[Nitin Bhadauria]

Dear All,

I am using samba 3.0.33-3.7.el5 with openldap for centralized
authentication and Nfs mount partition for storage drives.

Now the user who logged in the domain and using a shared drive, if they
stay ideal for approx 30min.
The drive get disconnected and when they try to open it 2-3 times it
start working again.

Please revert if any buddy else has faced the same problem.

Regards,
Nitin
