    <p>I'm interested in how other people code this because I'm either not understanding it properly or I'm missing something or perhaps even I'm doing it right!</p> <p>First of all, this is NOT an Active Directory instance of LDAP its OpenDS which other than some syntactical differences shouldn't much matter. </p> <p>So assume I have my tree structure setup something like this:</p> <pre><code>-dc=somedomain,dc=com -uid=rootuser -ou=Group1 -uid=username1 -uid=username2 -ou=Group2 -uid=username3 -uid=username4 </code></pre> <p>In order to authenticate as the 'rootuser' I would need to pass the fully qualified Username when I create my System.DirectoryServices.DirectoryEntry object, in this case:</p> <p>uid=rootuser,dc=somedomain,dc=com</p> <p>but for any other user in the tree I have to know in advance what LDAP path to append to the username to have them authenticate thru. So for example this will fail:</p> <p>uid=username1,dc=somedomain,dc=com</p> <p>but this will work:</p> <p>uid=username1,dc=somedomain,dc=com,ou=Group1</p> <p>So my question is how do you handle this when you don't know at login time what specific group a user belongs to to build that path? The only way I can figure to do it is to make the initial call as 'rootuser' so I have access to the entire tree then use System.DirectoryServices.DirectorySearcher to scan it for that particular user (i.e. username1)</p> <pre><code>using (DirectorySearcher searcher = GetDirectorySearcher()) { searcher.Filter = "(&amp;(objectClass=person)(uid=" + userName+ "))"; SearchResult result = searcher.FindOne(); return result.GetDirectoryEntry().Path; } </code></pre> <p>at that point I have the path for the user I want to login and I can proceed with the actual auth. Am I way off base here or is this generally how it is done?</p> <p>thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
