Hi,
I am trying to integrate MonoX with our ActiveDirectory server following your tutorial at http://www.mono-software.com/blog/post/Mono/92/MonoX-Active-Directory-integration/
I am getting the following error message:

[ProviderException: Unable to query Active Directory.]

MonoSoftware.MonoX.ActiveDirectoryRoleProvider.GetRolesForUser(String username) +913

System.Web.Security.RolePrincipal.IsInRole(String role) +164

System.Web.Configuration.AuthorizationRule.IsTheUserInAnyRole(StringCollection roles, IPrincipal principal) +123

System.Web.Configuration.AuthorizationRule.IsUserAllowed(IPrincipal user, String verb) +256

System.Web.Configuration.AuthorizationRuleCollection.IsUserAllowed(IPrincipal user, String verb) +199

System.Web.UI.WebControls.WebParts.PersonalizationProvider.DetermineUserCapabilities(WebPartManager webPartManager) +321

System.Web.UI.WebControls.WebParts.WebPartPersonalization.Load() +82

System.Web.UI.WebControls.WebParts.WebPartPersonalization.LoadInternal() +23

System.Web.UI.Control.InitRecursive(Control namingContainer) +210

System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +378

Anybody knows how to solve this?

Hi,
Could you please look into your log files (/MonoX/ApplicationData/Logs) to see if there are any detailed error descriptions related to this error? You can post the log file here or send me a private message.

Just as expected, the log file contains the following error message:

System.DirectoryServices.AccountManagement.PrincipalOperationException: Information about the domain could not be retrieved (1355).

This is probably caused by the DNS misconfiguration on your network. There are lot of articles on this topic:

Basically, you should ask the network administrator to verify the DNS entries for the domain controllers in your network. It appears that adding the IP address of your domain controller (which you are trying to connect) as the first entry in the DNS server list on the Web server machine also works. More information is available on the URLs I posted above.
