I have been trying to print the lastLogin time from active directory, its taken about an hour of coding testing and googling,  but I have done it.

First you have to get your AD entry.  Now I work in a place with a few domains so I narrowed my search down a bit by domain, but I bet you can figure out how to tweak it.

Then there is some funky code to convert the AD largeint into a date time and there you are all done

(This is an example so as for naming and exception handling i recommend you do it right)

string login=”funky\\simon”;string[] keys= {“displayName”,”LastLogon”,”mail”};string domain,name;

domain=login.Split(‘\\’)[0];name=login.Split(‘\\’)[1];

System.DirectoryServices.DirectoryEntry o=      new System.DirectoryServices.DirectoryEntry(“LDAP://dc=” + s + “,dc=binaryjam,dc=com”);

System.DirectoryServices.DirectoryEntry p=null;

System.DirectoryServices.DirectorySearcher search=                     new System.DirectoryServices.DirectorySearcher(o);

search.Filter = String.Format(“(SAMAccountName={0})”, name);

foreach (string key in keys){   search.PropertiesToLoad.Add(key);}

p=search.FindOne().GetDirectoryEntry();

foreach (string key in keys) {

string adDets=key + ” – “;

try {   if(key==”LastLogon”) {      ActiveDs.IADsLargeInteger li=((ActiveDs.IADsLargeInteger)(p.Properties[key].Value));      long date = (long)li.HighPart << 32 | (uint ) li.LowPart;      DateTime time = DateTime.FromFileTime( date );      adDets+=time.ToString();   }   else {      adDets+=p.Properties[key].Value.ToString();   }

   //Here I add asDets to a listBox but you do what you like with it}catch {//Yes I am a bad man, you do it right}

}

I have the followng articles to thank
