[Sahana_proj] Re: SHMACL

[Turner Hayes]

As a minor note, in implementing the system, I made the decision to 
create another table that maps a task id to function name (similar to 
the table that links role_id to a role name), due to some complications 
that I encountered in coding. I have tested the system on one function 
so far, and  it seems to work fine. I am now working on an interface to 
manage the system within Sahana (defining new roles, assigning users to 
roles, etc.).
