Customized sharepoint portal is not accessible to normal users unless a site admin access the site o


Hello there

I have created a sharepoint portal and customized it. I have created my own master page and there are many webparts implemented. This has been hosted in a MOSS server. When a normal user is trying to access the portal first thing in the morning, he is getting a "You are not authorized to view this page" error. But when a site admin access the site, there is no issue and he is able to access the site. The site admin does nothing in the site and once he has logged in to the site,  the user is able to access the site without any trouble.

I have tried to look into the master page gallery and has given full access to the users for "Style Resource Readers" user group. Even now the user is facing the same issue.

Kindly help in this regards,

Quick way to prevent users from creating sub-sites under their my site?


Probably something very easy that I've just missed... but we want to prevent our users from building loads of sites and such under their my site in SP 2010. Hopefully this will encourage them to use other areas that we are building for them instead of the my site!

Thanks for any input you can provide.

Performing CRUD operations using ASP.NET Web API - Part 1

ASP.NET Web API is a framework that simplifies the creation of HTTP services. We can build loosely coupled services as Web API follows REST architecture. Another advantage of using HTTP services is that it can be consumed by a wide range of clients.

MS SQL Server: Disconnect Users From Database - Kill User Session

Enabling Users to Maintain SharePoint Content

When SharePoint is installed as a corporate intranet, there is a considerable amount of effort involved in maintaining the content to keep the site relevant. As we discussed in the first few parts of this series, SharePoint has many built-in features to reduce the burden on the site administrator.

Some areas of the site usually contain less-dynamic information. Internal memos and corporate policies are common examples of this information. One option for this information is to post these documents in a document library. Documents in a library are often stored in a few different formats: Word, Acrobat (PDF), or HTML. Each of these formats has its drawbacks.

How to Perform SQL Server Row-by-Row Operations Without Cursors

SQL cursors have been a curse to database programming for many years because of their poor performance. On the other hand, they are extremely useful because of their flexibility in allowing very detailed data manipulations at the row level. Using cursors against SQL Server tables can often be avoided by employing other methods, such as using derived tables, set-based queries, and temp tables

Need help redirecting users to personalized page


 Hi, first timer here so be gentle.


I've been able to create a cool little website, it's up and running with users logging in and out, I created roles so my administrative team can see sensitive data that's not available to regular and anonymous users.

Now they would like me to create a page specific to each user.  For instance when user A logs in they are redirected to a page that has information that pertains to user A only (like a list of their benefits/ their remaining vacation time). This page needs to be accessible only to user A. 

I've watched a ton of the videos but have yet to see one that covers this topic, any help would be great!!!





Intranet Users Challenged When Using Windows Integrated Security


We've setup an intranet site using Windows Integrated Security. Its up and running and users can access it. However, they are being challenged with a login dialog for the server when they initially access the site.

Isn't is possible to configure the server so that the users aren't challenged AND are recognized as being already authenticated by Windows? We're trying to go with a seamless experience, whereby all they have to do is login to their machine like normal and then go from there.

Users getting logged out because HttpContext.Current is null


We've  been trying to fix this one for a couple years, and I'm just out of ideas, so any help is really appreciated!

We've got a fairly large, complex web application that uses Forms Authentication to authenticate users.  Throughout the application we store and retrieve information about users in the Session object, and in some cases in cookies.  In a couple places we check for the existence of the context, and if it's null we send the user back to the login page to re-establish the session. 

Just a quick run-down of this web app: C#, .NET 3.5, IIS 6, ASP.NET State Service to manage session

As for the session timer, we use our own home-grown timer, which is basically a client-side timer, which is backed up by a check to the SQL database to see when their last activity was.  This seems to work well for us.  It's not perfect, but it allows us to notify the user before the session times out, and allows us to be certain we're not logging a user out before their 60 minutes of inactivity is up.

What's happening is that certain users are being logged out after just a few minutes.  We've eliminated the timer as a cause and believe what's happening is the HttpContext.Current is null, so the user is logged out.  We do not know why the HttpContext.Current is null, and I underst

Getting users list reporting to manager from LDAP

Use Membership but bypass / disable password usage for users


I have an application that does LDAP authentication. The authentication is done on the code behind page of my Login.aspx page. Once the user passes LDAP authentication, a cookie is set and I redirect:

FormsAuthentication.RedirectFromLoginPage(UserName.Text, False)

I would like to setup membership in my application and keep track of some user information. But due to company security requirements, I cannot store user passwords on my application. That must stay on the LDAP server only.

Is there a way to store users but disable password storage on the aspnet_membership table?
