Hi chicks_in

It's certainly possible to authenticate a user with the LDAP provider's OpenDSObject method, but not recommended [1]

cDomain = "mydomain"
* Name of user to validate
* cUser = "firstname lastname"

* any OUs required to access user object
cOUString = "OU=Users,OU=Department"

* required DC string - replace .co.uk with .com or .wvr
cDCString = "DC=" + cDomain + ",DC=co,DC=uk"

* The path returned must be valid - able to create a user using
* VFP's GetObject() function - in order to work with OpenDSPath()
cPath = "LDAP://" + cDomain + "/CN=" + cUser + "," ;    + cOUString + "," + cDCString

* These credentials are used to authenticate to the AD
cUserName = "adminperson"
cPassword = inputbox("Password please")


oLDAP = getobject("LDAP:")
oUser = oLDAP.OpenDSObject(cPath, addbs(cDomain) + ;
          cUserName, cPassword, 0)
? oUser.Name

If all you want to do is let your users into the application based upon their login credentials; then what I do is pick the user name out of the sys(0) information and then check that against a user table in my application. This works for us inhouse. Obviously it doesn't implement LDAP but it might do what you want.

Is it possible to use 'REAL' LDAP instead of the IADsOpenDSObject and the 'LDAP Provider' ?

I need to verify a username and password through an application and it may not necessarily be the logged in user.   All I want to do is a simple LDAP bind to verify the user and password,  and I can't for the life of me find an already documented way to do it in VFP. 

I did it in the 90s with C on Win9x and Netware.  I did it a couple years ago with PHP on Linux and AD.  I can do it right now with ldapsearch on Linux and AD.    But it seems VFP on Win to a Windows Server is just not very popular at all. 

Is there a free .Net library I can use?   I can't seem to locate a library I can easily integrate into VFP.   Otherwise I'm stuck distributing cygwin to all the desktops so I can use *nix command line tools. :/

Sorry - I'm not a programmer, I just make stuff work

Answer 4

Yes, it is definitely possible to implement via Windows LDAP API calls.
