Ruby
Assume AD server talks LDAP.
<lang ruby>require 'rubygems' require 'net/ldap'
ldap = Net::LDAP.new(:host => 'hostname', :base => 'base') ldap.authenticate('bind_dn', 'bind_pass')
filter = Net::LDAP::Filter.pres('objectclass') filter &= Net::LDAP::Filter.eq('sn','Jackman')
- or
filter = Net::LDAP::Filter.construct('(&(objectclass=*)(sn=Jackman))')
results = ldap.search(:filter => filter) # returns an array of Net::LDAP::Entry objects
puts results[0][:sn] # ==> "Jackman"</lang>
Run BASIC
This allows the client on the web to see their directory. The user can click on any file or directory and this will give them the following options: [upload] data from their computer to the server [delete] data from their directory [rename] files [view] image files

Tcl
One can do it with the low level Connect to Active Directory based handle with this code:
This is just the basic setup. <lang tcl>set Username "TestUser" set Filter "((&objectClass=*)(sAMAccountName=$Username))" set Base "dc=skycityauckland,dc=sceg,dc=com" set Attrs distinguishedName</lang>
Now do the actual search. <lang tcl>set result [ldap::search $conn $Base $Filter $Attrs -scope subtree]</lang>
If we have only a single result its easy: <lang tcl>if {[llength $result] == 1} {
puts [dict get [lindex $result 0 1] distinguishedName]
}</lang>
Looping over the result set to output some values. <lang tcl>foreach pair $result {
lassign $pair cn attributes puts [dict get $attributes distinguishedName]
}</lang>
If you're bored you can also use this instead: <lang tcl>package require ldapx set conn [ldapx::connect $BindDN $Password] $conn traverse $Base $Filter $Attrs e {
puts [$e get distinguishedName]
}</lang>
VBScript
The search string and execution of the string <lang vbscript>strUsername = "TestUser" strQuery = "<LDAP://dc=skycityauckland,dc=sceg,dc=com>;"_
& "(&(objectclass=*)(samaccountname=" & strUsername & "));distinguishedname;subtree"
objCmd.ActiveConnection = objConn objCmd.Properties("Page Size")=100 objCmd.CommandText = strQuery Set objRS = objCmd.Execute</lang>
Doing something with a single result (this will output the returned users full DN) <lang vbscript>If objRS.RecordCount = 1 Then
WScript.Echo objRS.Fields("DistinguishedName")
End If</lang>
Doing something with multiple results (this will output each returned users full DN) <lang vbscript>If objRS.RecordCount > 0 Then
For Each objUser in ObjRS WScript.Echo objRS.Fields("DistinguishedName") Next
End If</lang>
