Does tableau support the concept of session variables? What I am looking for is to extract an attribute in LDAP for every users and store it in a session variable and then use this variable as a filter in a report.
Tableau does not support session variables. How about a parameter, though? You could load it with your values and use that to drive a filter.
If you're viewing the report on Tableau Server, you don't even need to worry about storing the info in Tableau - just pass the value you want to filter on on the query string: http://server.com/views/MyWorkBook/MyView?LDAPAttribute=Foo
