I have to populate my autocomplete PeopleEditor-like control based on brililant ASPTokenInput with all people from my AD domain. Reflecting PeopleEditor shows a real mess in their Active Directory search engine and all potentially helpful classes are internal.
My test method works fine, but I need to get ALL users from AD(not sharepoint site ones) to populate my list:
public string GetUsers(string filter)
{
var spWeb = SPContext.Current.Web;
SPUserCollection allusers = spWeb.AllUsers;
List<SPUser> users = allusers.Cast<SPUser>().ToList();
var query = from spUser in users.Select(usr => new {id = usr.ID, name = usr.Name})
.Where(p => p.name.IndexOf(filter, StringComparison.InvariantCultureIgnoreCase) >= 0)
select new {id = spUser.id.ToString(), spUser.name};
return new JavaScriptSerializer().Serialize(query);
}
How can I query active directory like this? Is it possible to retrieve all AD connection settings from sharepoint itself? I need just id and user name to fill my dropdownlist Converting this to SPUserCollection is another big deal.
It would be great to use some built-in SP methods like this:
[SubsetCallableExcludeMember(SubsetCallableExcludeMemberType.UnsupportedSPType)]
public static IList<SPPrincipalInfo> SearchWindowsPrincipals(SPWebApplication webApp, string input, SPPrincipalType scopes, int maxCount, out bool reachMaxCount)
Solution was simple, the only thing I needed was SharePoint Group search implementation (If specified in Field Editor Control). SP has a nice built-in method, so I use it.
/// <summary>
/// Provides searching for AD or SharePoint group if specified in field setting
/// </summary>
public static class ActiveDirectorySearchProvider
{
public static IList<SPPrincipalInfo> Search(string filter, string selectionGroup, string principalType)
{
var site = SPContext.Current.Site.WebApplication;
bool reachmaxcount;
var scope = SPUtils.GetSpPrincipalType(principalType);
if (!String.IsNullOrEmpty(selectionGroup)) //search for users in SPGroup if present
{
var rawSPGroupList = SPUtility.GetPrincipalsInGroup(SPContext.Current.Web, selectionGroup, 100,
out reachmaxcount).ToList();
string lowerFilter = filter.ToLowerInvariant();
var filteredGroupList =
rawSPGroupList.Where(
pInfo =>
pInfo.LoginName.Substring(pInfo.LoginName.IndexOf('\\') + 1).StartsWith(lowerFilter) ||
pInfo.DisplayName.ToLowerInvariant().StartsWith(lowerFilter) ||
pInfo.DisplayName.ToLowerInvariant().Substring(pInfo.DisplayName.IndexOf(' ') + 1).StartsWith(
lowerFilter)).ToList();
return filteredGroupList;
}
return SPUtility.SearchWindowsPrincipals(site, filter, scope, 100, out reachmaxcount); //Search in AD instead
}
