[Building Sakai] what is "tool.permission" in method getAuthzGroupsIsAllowed() ?

[Stephen Marquard]

This particular method is more like "search for a list of authzgroups in which this user has a permission".

A typical case would be to get the list of groups in a site, then find out which ones the user can do something in (like create an announcement), by passing the whole list of groups and getting back a subset, or get a list of sites in which the user has a particular permission.

Cheers
Stephen

Hi Vo,

"tool.permission" will be a specific permission you want to check for,  
ie one of the manypermissions that tools register, ie annc.new,  
annc.read, content.new etc

Take a look in the Admin > Realms > Role and you'll see the complete  
list of registered functions. Essentially you can search for a user  
with a specific permission in a site.

cheers,
Steve
