View 4 RepliesI'm a developer new to asp.net 3.5. My client asked if there were any implications of using Linq to SQL data sources with mirrored clustered servers with Failover clustering.
So my questions are can you use Linq to SQL with mirrored Clustered Servers?
If yes to the above, do you need to add or modify any code for mirrored Clustered Servers?
I am trying to set up my web site on a stand alone server using Windows Server 2003 with IIS 6 which will access SQL server database (2008) on windows 2008 R2 server (also not in the domain) I am using form authentication and I have configured a custom identity account in IIS6. The local account is on both servers with same password and I have registered the account using aspnet_regiis.exe -ga The application pool in my iis6 has the custom local account set as the identity and my web.config file has the appropriate tags in the system.web element <identity impersonate="true" />
The problem is the local account does not seem to get passed to the sql server. Right now my iis settings are anonymous access (using the local acct vs isr) and no authentication specified under that - I did try Integrated and basic but it prompts for the username and password which I do not want. One article I read stated this: windows authentication does not support delegation (passing credentials from one server to another) and is limited to the one hop rule, only a primary token can be passed to a second server. windows
authentication on iis (all versions) gives the thread a secondary(impersonation) token which can not be used to access any network resouce
We have an IVR product that reads a configuration database for callflow information. I am writing a tool for our implementation team that will allow them to add/delete/update the data in the configuration database. Once the tool is in production, the implementer will use only the production release of the tool to modify the configuration database in all four of the IVR regions (Dev, QA, Cert, and Prod). Each region has its own database with identical schemas. The tool has 'tabs' across the top for each region. If a user is currently working in the Dev region and clicks the QA tab, how do I switch my connection from the Dev db server to the QA db server?
