I am trying to understand the simultaneous-use doc

I am having trouble with a part that says:

Note that you need to add the Simultaneous-Use parameter to the check item (first line), not the reply item, using the ':=' operator.

I am not sure where to add the Simultaneous-Use parameter. Does it go in ldap.attrmap.config ?

No. See "man users", or "doc/rlm_sql" Alan DeKok.
