How to verify if an user is part of a given group?

If you are using the function isusermemberofgroup() it may be because you are logged in as a basic user, for which the function is not allowed in the context of.

From the documentation: "When the expression function is passed a high privacy group as a parameter AND is executed within the context of a basic user who is not a group administrator AND is passed the username of another user, it returns false instead of true.

A basic user is not allowed to know whether another user is a member of such groups."

If this is the case, a workaround you could use is calling the 'getdistinctusers()' scripting function to return a list of the users from a passed in group, and then search the returned array/list to see if it contains the user name with the 'contains()' function.

Hope this was helpful.
