Site Collection Administrator on a FBA getting Access Denied errorsSite Collection Administrator on a FBA getting Access Denied errors

 

One of my customers was facing an issue with one of the Forms based authentication sharepoint web application where the site collection administrators were getting ACCESS DENIED errors. We spend a whole lot of time in figuring out what was the issue and for no reason were were getting a SQL Exception as below:

 

[SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

In no way that we were using the out of the box ASP Net Membership provider we had built our own custom Membership Provider that doesn’t leverage SQL Server. After all that debugging finally we decide to take a look at the web.config file and VIOLA we found the issue J.

 

Basically the problem was the customer’s IT/Operations team had placed the Membership/Roleprovider entry in a incorrect system.web section of the web.config file because of which it was picking up the membership provider from the *Machine.config* (the default ASPnetMembership Provider) file.  

Machine.Config default membership provider:

  <system.web>

    <processModel autoConfig="true"/>

    <httpHandlers/>

    <membership>

      <providers>

        <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="LocalSqlServer" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" applicationName="/" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="1" passwordAttemptWindow="10" passwordStrengthRegularExpression=""/>

      </providers>

    </membership>

    <profile>

      <providers>

        <add name="AspNetSqlProfileProvider" connectionStringName="LocalSqlServer" applicationName="/" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

      </providers>

    </profile>

    <roleManager>

      <providers>

        <add name="AspNetSqlRoleProvider" connectionStringName="LocalSqlServer" applicationName="/" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

        <add name="AspNetWindowsTokenRoleProvider" applicationName="/" type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

      </providers>

    </roleManager>

  </system.web>

 

Wrong Section of the web.config :

<location path="_layouts/images">

    <system.web>

    <membership defaultProvider="ABCMembershipProvider">

      <providers>

        <add name="ABCMembershipProvider" type="ABC.Web.Security.ABCMembershipProvider,ABC.Web.Security.AuthenticationProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=daf6fd1bbe0cfc20" />

      </providers>

    </membership>

    <!-- role provider -->

    <roleManager enabled="true" defaultProvider="ABCRoleProvider">

      <providers>

        <add name="ABCRoleProvider" type="ABC.Web.Security.ABCRoleProvider,ABC.Web.Security.ABCRoleProvider,Version=1.0.0.0, Culture=neutral, PublicKeyToken=daf6fd1bbe0cfc20" />

      </providers>

    </roleManager>

      <authorization>

        <allow users="*" />

      </authorization>

    </system.web>

  </location>

 

So after placing the Membership provider and Role provider entry in the correct location it started working. So Please check the web.config file properly and make sure the entries are placed in the appropriate sections.
