I got the following snippet ( SomeName / SomeDomain contains real values in my code) var entry = new DirectoryEntry("LDAP://CN=SomeName,OU=All Groups,dc=SomeDomain,dc=com"); foreach (object property in entry.Properties) { Console.WriteLine(property); } It prints OK for the first 21 properties, but then fail with: COMException {"Unknown error (0x8000500c)"} at System.DirectoryServices.PropertyValueCollection.PopulateList() at System.DirectoryServices.PropertyValueCollection..ctor(DirectoryEntry entry, String propertyName) at System.DirectoryServices.PropertyCollection.PropertyEnumerator.get

I am porting an old 3 2-bit COM component that was written in VB6 for the purpose of reading and writing to an Active Directory server. The new solution will be in C# and will use SQL CLR user functions. The assembly that I am trying to deploy to SQL Server contains a reference to System.DirectoryServices . The project does compile without any errors but I am unable to deploy the assembly to the SQL Server because of the following error: Error: Assembly 'system.directoryservices, version=2.0.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a.' was not found in the SQL catalog. What are the

I'm currently trying to authenticate via Active Directory Services using the PrincipalContext class. I would like to have my application authenticate to the Domain using Sealed and SSL contexts. In order to do this, I have to use the following constructor of PrincipalContext (link to MSDN page) : public PrincipalContext( ContextType contextType, string name, string container, ContextOptions options ) Specifically, I'm using the constructor as so: PrincipalContext domainContext = new PrincipalContext( ContextType.Domain, domain, container, ContextOptions.Sealing | ContextOptions

I'm getting the following intermittent errors related to querying AD using DirectorySearcher.FindOne() or FindAll() . System.OverflowException: Arithmetic operation resulted in an overflow. at System.DirectoryServices.SearchResultCollection.ResultsEnumerator.GetCurrentResult() at System.DirectoryServices.SearchResultCollection.ResultsEnumerator.get_Current() at System.DirectoryServices.SearchResultCollection.ResultsEnumerator.System.Collections.IEnumerator.get_Current() This is happening in a web app and seems to happen after the app has been running for several hours. This is a documented

What I mean is that right now I am using System.DirectoryServices.AccountManagement and if I use UserPrincipal class I only see the Name, Middle Name, etc so in my codes it like UserPrincipal myUser = new UserPrincipal(pc); myUser.Name = "aaaaaa"; myUser.SamAccountName = "aaaaaaa"; . . . . myUser.Save(); How would I see the attribute like mobile or info? Raymund The proper way of doing it is by using PrincipalExtensions where you extend the Principal you are after and use the methods ExtensionSet and ExtensionGet as explained here . In this case, you need to go one level deeper - back into the

I have a long running process that needs to do a lot of queries on Active Directory quite often. For this purpose I have been using the System.DirectoryServices namespace, using the DirectorySearcher and DirectoryEntry classes. I have noticed a memory leak in the application. It can be reproduced with this code: while (true) { using (var de = new DirectoryEntry("LDAP://hostname", "user", "pass")) { using (var mySearcher = new DirectorySearcher(de)) { mySearcher.Filter = "(objectClass=domain)"; using (SearchResultCollection src = mySearcher.FindAll()) { } } } } The documentation for these

I am throwing together a quick C# win forms app to help resolve a repetitive clerical job. I have performed a search in AD for all user accounts and am adding them to a list view with check boxes. I would like to default the listviewitems' default check state to depend upon the enabled/disabled state of the account. string path = "LDAP://dc=example,dc=local"; DirectoryEntry directoryRoot = new DirectoryEntry(path); DirectorySearcher searcher = new DirectorySearcher(directoryRoot, "(&(objectClass=User)(objectCategory=Person))"); SearchResultCollection results = searcher.FindAll(); foreach
