[Samba] Slow Domain or Member Browsing

[Raymond]

Successfully installed Samba3 utilizing OpenLDAP, nsswitch and pam-ldap. 
Additionally, the smbldap-tools and phpLDAPadmin are excellent.

However, member browsing either in workgroup or domain mode  is extremely 
slow. Once a member resource are accessed (say, a server share), performance 
is good.

Local and perferred master are set to yes with an OS value of 65.
