I have next issue: i have edb file(Exchange Server 2013), and i can get mailbox guids from it. One of mailbox is PublicFolder mailbox. It's impossible to find out if mailbox is PF, or just simple user's mailbox.
I already have functionality to get all information of mailbox by it's guid from AD.
string filter = #"(&(objectClass=user)(msExchMailboxGuid=" + ESWUtils.GetADGuidString(guid) + "))";
search.Filter = filter;
search.SearchScope = SearchScope.Subtree;
search.PropertiesToLoad.Add("mail");
search.PropertiesToLoad.Add("displayname");
search.PropertiesToLoad.Add("samaccountname");
...
Is it possible to find out, that guid belongs to PF mailbox, from AD?
In Exchange 2013, Public Folders are moved into mailboxes and out of their own database. Looks like the easiest way is to look at the msExchRecipientTypeDetails attribute.
search.Filter = "(msExchRecipientTypeDetails=68719476736)"
Combine that with your other search criteria.
Running a Get-Mailbox -PublicFolder on the mailbox will show the RecipientTypeDetails listed as PublicFolderMailbox. 68719476736 is the bitwise identifier that matches on the user attributes.

We have Linux hosts that are bound to our Active Directory Domain user Samba/Winbind to be a member server - for users to get access to the servers we use a domain group placed into the sshd_config. So user gets added to group and then in theory they can login - that was the plan.
At the moment we can add a user to the group - and if that group has never been used before the server will reach out and grab the group membership. But once that has been done the group membership does not refresh - without going to the extremes of removing tdb files and rebinding the machine to the domain which is a mess.
Has anyone ever got around this problem?
What is annoying is that if I ssh onto the box - add a user to the AD group then 'su' to the user the groups are refreshed. However that does not work if you 'sudo su' (I don't want people's passwords)

map acl inherit = yes

I am wondering if the issue is SSH looking at the group and this does not trigger an event to go and check the group membership in AD?
Can get around this with using local groups and domain users - but this is annoying that surely this is something that fundamentally should work
Thanks
Your smb.conf is borked or you are using sssd, if the latter, this has nothing to do with Samba, if the former, please read this:

I am trying to get some user attributes from Active Directry using Windows LDAP API. I am using:
Active Directory Version: The one that comes with Windows Server 2012
LDAP version: 3
Wldap32.lib version: The one that comes with Windows 10 x64
Eg:
PCHAR myAttributes[4];
myAttributes[0] = "DistinguishedName";
myAttributes[1] = "DisplayName";
myAttributes[2] = "PasswordExpired";
myAttributes[3] = "mail";
ldap_search_s(
myLdapConnection, // Ldap connection
myDomain, // DN to start search
LDAP_SCOPE_SUBTREE, // Scope
myFilter, // Filter
myAttributes, // Retrieve list of attributes
0, // Get both attributes and values
&mySearchResult // [out] Search results
);
It returns DistinguishedName, DisplayName and mail attributes, but does not reuturn the PasswordExpired attribute.
I queried with some other attributes and it looks like it does not return attributes with boolean values as well as the EmailAddress attribute.
Why does it not return PasswordExpired attribute?
What about EmailAddress ?
Is there a difference between EmailAddress and mail ?
There is no PasswordExpired LDAP attribute in Active Directory. To build your query look at this URL for attribute names in standard Active Directory schema https://msdn.microsoft.com/en-us/library/ms675090(v=vs.85).aspx. To check if password for given account is expired you'll need to check userAccountControl attribute, which is actually value storing flags of different states of user account https://msdn.microsoft.com/en-us/library/ms680832(v=vs.85).aspx. There is IADsUser interface that will translate this all for you in case you don't have to stick just to LDAP https://msdn.microsoft.com/en-us/library/aa746343(v=vs.85).aspx
You will find current primary email address in mail attribute. There is no EmailAddress LDAP attribute, unless you meant E-mail-Addresses which is CN for the same schema attribute as mail, so no difference there.
See above. In general if you do not have compelling reason to stick just to C/LDAP I'd recommend you to use .Net Framework instead. Otherwise you have a lot of work ahead of you - not just interpreting bit flags like in case of password expiration but possibly also with different authentication methods, different structures capturing time and date, accounting for timezones, UTF, chasing referrals and other stuff you might need depending on complexity of what you want to achieve. You will be productive much faster in .Net Framework. See DirectoryServices https://msdn.microsoft.com/en-us/library/mt481534(v=vs.110).aspx namespace or Security namespace https://msdn.microsoft.com/en-us/library/mt481561(v=vs.110).aspx for details.
I have this problem: we try to authenticate a user against an Active Directory that uses ForeignSecurityPrinciple to map users from different domains.
We have several groups that are stored inside a single domain and users that are coming from different domains.
The problem we have here is that we cannot get the real user name from ForeignSecurityPrinciple.
We tried to use the guidelines from here:
http://www.brandonclaps.com/?p=57
but with no luck.
When we tried to edit the entry for group that had 3 members, we found this next to the member field:
CN = S-1-5-21-other numbers, CN=ForeignSecurityPrinciple; DC=DomainName, DC=local
Do you have other solutions for retrieving the username against Active Directory using ForeginSecurityPrinciple ?
Is there any recommendation for using that?
Thanks a lot in advance
I created an Active Directory domain name 'ADDOMAIN2' having a group name "CommonUsers" having 8 users. but when I do a Directory Search for users in group "CommonUsers" it returns zero result. hers is my code
DirectorySearcher searcher = new DirectorySearcher();
DirectoryEntry directoryEntry = new DirectoryEntry(string.Format("LDAP://{0}", "ADDOMAIN2"), "Administrator", "p#S$w0rd");
string dnPath = directoryEntry.Properties["distinguishedName"].Value.ToString();
// string path = string.Format("LDAP://{0}/{1}{2}", "ADDOMAIN2", "", dnPath);
string path = "LDAP://ADDOMAIN2/CN=CommonUsers,DC=ADDomain2,DC=ADDomain01,DC=WaveDomain";
directoryEntry.Path = path;
searcher.SearchRoot = directoryEntry;
searcher.Filter = "(&(objectCategory=person)(objectClass=user))";
SearchResultCollection rs = searcher.FindAll();
Any Idea what is wrong here?
Thanx
Try using some external LDAP browser (like the old and free version 2.6 of Softerra LDAP Browser) to check whether your query string is really pointing to the correct location.
DirectorySearcher is not used to find users inside a group. It's used to find objects under a base path. Since there is no user objects placed under your AD group object, you won't find anything.
In most cases, you can find the user objects in an AD group from its member attribute. Beware that AD group can contain either group or user. So, some of the entres there may be group. In some cases, the member attribute does not contain AD group nor AD user, it's containing a Foreign Security Principal. This happens if your user is coming from another forest. The primary group is also handled differently. Even "Domain User" is primary group of most of the users in AD, its member attribute doesn't contain anything at all. There are a lot other oddities that makes enumerating an AD group object really hard.
Fortunately, in .NET 3.5, Microsoft provides some useful classes in the framework to do the dirty work for you. Check out System.DirectoryServices.AccountManagement
To get some quick examples, you can check out this codeproject article
Your code should be something like this.
PrincipalContext context = new PrincipalContext(ContextType.Domain, "yourdomain.com");
GroupPrincipal groupPrincipal = GroupPrincipal.FindByIdentity(context, IdentityType.SamAccountName, "Domain Users");
foreach (Principal principal in groupPrincipal.GetMembers(false))
{
Console.Out.WriteLine(principal.DistinguishedName);
}
Console.In.ReadLine();
The active directory I have to deal with is laid out as such: the domain contains many OUs. One of these OUs is named "Primary OU". Within this OU are several OUs named with location of global offices (ie "Chicago" "Paris").
Any user account that is an actual flesh and bone person is put into the OU named for the office they work in as their primary OU. Any user account that is an alias, generic account, or otherwise not directly tied to a real person, has the "Primary OU" OU set as their primary OU.
Data-wise, this primary OU distinction is the only thing that indicates which users are real people, and which users are not. There is no group that contains only real people, no indicator in any field that they are real people or not, and making any changes to active directory or any user accounts is strictly forbidden.
My task is writing a query that will only get all actual flesh and bone people.
Unfortunately LDAP is not exactly my strong suit and the only way I've come up with is searching each of these office sub OUs individually and putting all the results together, but there are a lot of offices and it would require a change to the query if any offices were added, which I need to avoid.
Is there a way to query all users within a particular OU's "sub" OUs, but not return any users directly in the parent OU?
Yes, sure - you would need to:
1) Bind to the particular OU
DirectoryEntry myOU = new DirectoryEntry("LDAP://OU=MyOU,......,DC=MyCompany,DC=com");
2) Enumerate all its sub-OU's
DirectorySearcher subOUsearcher = new DirectorySearcher(myOU);
subOUsearcher.SearchScope = SearchScope.OneLevel; // don't recurse down
subOUsearcher.Filter = "(objectClass=organizationalUnit)";
foreach(SearchResult subOU in subOUsearcher.FindAll())
{
// stick those Sub OU's into a list and then handle them
}
3) One-by-one enumerate all the users in each of the sub-OU's and stick them into a global list of users
DirectorySearcher userSearcher = new DirectorySearcher(myCurrentSubOu);
userSearcher.SearchScope = SearchScope.OneLevel; // don't recurse down
userSearcher.Filter = "(objectClass=user)";
foreach(SearchResult user in userSearcher.FindAll())
{
// stick those users into a list being built up
}
4) Return that list
Marc
// Create a new DirectorySearcher that starts at the root.
// You can start it anywhere you want though
// by providing a value in the DirectoryEntry constructor.
DirectorySearcher searcher = new DirectorySearcher(new DirectoryEntry());
// Set the scope to Subtree in order to search all children.
searcher.SearchScope = SearchScope.Subtree;
// Set the filter to only look for Organizational Units
// that have the name you are looking for.
searcher.Filter = "(&(objectClass=organizationalUnit)(name=" + ouName + "))";
// If you are looking for only one result then do the following two things.
SearchResult result = searcher.FindOne();
DirectoryEntry newDir = result.GetDirectoryEntry();
