AstroGrid-D VO Management

VO Management is separated into three different blocks:

1st Block: User Registration and VO Administration
is done using the VOMRS server from OpenScienceGrid, which allows

users to registrate their certificate
local Registration Authorities to confirm their request
VO-Managers to define their membership in differnt VOs

2nd Block: Get VO-member lists from VOMRS:

http/https based query process extracting VO-Member lists from VOMRS
every VO-Member has a unique VO-Memeber-id, which allows mapping to user-id on local systems

3rd Block: Update local gridmap-files

update gridmap-file, taking local preferences and mapping schemes into account
create new grid users locally
regular update via cron-job
