Section Access (Data Reduction) using Active Directory

[AC3]

Purpose:  Use Active Directory Groups to determine what data to display for each user.

After piecing together many articles and community advice, I created this script and hope it's useful to others.   It reads Active Directory for members in a particular group and displays only the data according to the User's group(s). 

Please refer to  Introduction to Section Access  for an introduction to Section Access.

In Document Settings on the Opening tab,  Click the Initial Data Reduction Based on Section Access option.

You will need the full canonical name of your Active Directory.  Replace text in orange with the parts of the canonical name as needed.

The script runs in the Hidden Scripts section.

OLEDB CONNECT TO [Provider=ADsDSOObject;Encrypt Password=False;Data Source=LDAP:// DC=DCHOST,DC=DCCOM;Mode=Read];

DataSecurity:

//Users in the East Group

Load Upper(sAMAccountname) as NTNAME, 'East' as Zone, 'USER' as ACCESS;

SELECT sAMAccountname

FROM 'LDAP:// DC=DCHOST,DC=DCCOM'

WHERE objectCategory='person'

   AND objectClass='user'

   and memberOf='CN=EASTGROUP,DC=DCHOST,DC=DCCOM';

//Users in the West Group

Concatenate

Load Upper(sAMAccountname) as NTNAME, 'West' as Zone, 'USER' as ACCESS;

SELECT sAMAccountname

FROM 'LDAP:// DC=DCHOST,DC=DCCOM'

WHERE objectCategory='person'

   AND objectClass='user'

   and memberOf='CN=WESTGROUP,DC=DCHOST,DC=DCCOM';

//Users who can see everything

Concatenate

Load Upper(sAMAccountname) as NTNAME, '*' as Zone, 'ADMIN' as ACCESS;

SELECT sAMAccountname

FROM 'LDAP:// DC=DCHOST,DC=DCCOM'

WHERE objectCategory='person'

   AND objectClass='user'

   and memberOf='CN=ALLGROUP,DC=DCHOST,DC=DCCOM';

STAR is *;

SECTION Access;

LOAD

  ACCESS,

  NTNAME

Resident DataSecurity;

SECTION Application;

LOAD

  NTNAME,

  Zone

Resident DataSecurity;

Drop Table DataSecurity;

Note: Changes with Qlikview 12: A Listbox to display Zone will now display the *.  To hide the * in the Listbox, use this expression for the Field:  =aggr(only({<Zone={'?*?'}>}Zone),Zone)

Hi

This looks great.

Can we achieve hierarchy based section access as well with this?

Thanks

Satish,

You should be able to depending on how your AD groups are setup and you'll have to supplement the script above to accommodate the different levels. See here for more info: Authorization using a Hierarchy

You can't use NTNAME in Qlik Sense.
