[Samba] Planning to upgrade to samba-3.0.33-3.37.el5.x86_64 version from samba version 3.0.25b-1.el5_1.4 ------------ queries needed to be answered.

[Shome, Prasanjit (TCS)]

Hi All,
        Need help regarding the samba version samba-3.0.33-3.37.el5.x86_64


1)      In the samba version (samba-3.0.33-3.37.el5.x86_64) that we are planning to use , if we put multiple password server names like the one shown below

        workgroup = EUROPE         --------- we do have a domain named as EUROPE [ as per windows team ]
        password server = EUREDD-HUB10 EUREDD-HUB09 *
        security = domain

a)      Is this the right format ?
b)      Is there any provisioning of any load balancing of user requests for authentication if we use multiple password servers ?

2)      what are the scenarios or conditions in which samba will hop to another password server mentioned in the list ?

3)      can you let us know the working functionality how samba client tries to connected to DC and eventually to the samba Linux (in our environment) server ?

4)      In our environment, we have seen recurring connectivity issues over WAN (primarily) and authentication failure issues (shown below) while using samba version 3.0.25b-1.el5_1.4. Can you please let us know if there is any bug fixes made against those concerned issues if we upgrade to samba-3.0.33-3.37.el5.x86_64.
