Re: [Urgent] Samba problem
I can see one very visible problem:
In the service definition for webdata, you have guest ok = no but public = yes. The public setting is just a synonym for guest ok. Setting these to two different values is not a good idea.
Also, I don't know much about using LDAP for Samba, but should security be set to security = user instead of security = share? The guest ok/public setting lets anyone connect to the share, so maybe to allow for proper LDAP authentication you need to set guest ok = no (the default, so you can delete both of those settings) and set security = user. I don't know, but I would try it.
