GrouperSystem is the root-like principal used to manage assignment of privileges in Grouper. In addition to GrouperSystem, externally authenticated members of the wheel group can choose when to act with root-like privileges.
If you've enabled the wheel group, you must create it and add members. GrouperShell acts as GrouperSystem and can bootstrap the necessary naming stem(s), group, and memberships.
The wheel group is enabled and named in conf/grouper.properties :
# A wheel group allows you to enable non-GrouperSystem subjects to act # like a root user when interacting with the registry. groups.wheel.use = true # Set to the name of the group you want to treat as the wheel group. # The members of this group will be treated as root-like users. groups.wheel.group = etc:sysadmingroup
To automatically create the wheel group :
configuration.autocreate.system.groups = true
To create the wheel group using GrouperShell :
gsh 0% addRootStem("etc", "Grouper Administration") stem: name='etc' displayName='Grouper Administration' uuid='f7687876-2c94-4635-997c-f2793fb8152d' gsh 1% addGroup("etc", "sysadmingroup", "SysAdmin Group") group: name='etc:sysadmingroup' displayName='Grouper Administration:SysAdmin Group' uuid='6f77fb36-b466-481a-84a7-7af609f1ad09
Whether you've set the wheel group to be automatically created, or you've used GrouperShell to create it, you'll need to add members to the wheel group. Once the wheel group is established, and things are working, the person designated as wheel can use the UI or use GrouperShell to manage other wheel members. Here is an example using GrouperShell:
gsh 0% addMember("etc:sysadmingroup", "SD00125") true
In this example "SD00125" is the subjectId of a person, as determined outside of gsh by, in this case, an LDAP query to a directory that acts as a subject source to Grouper:
% ldapsearch \-b dc=kitn,dc=edu uid=tbarton dn: kitnEduPersonRegId=SD00125,ou=people,dc=kitn,dc=edu objectClass: top objectClass: person objectClass: inetOrgPerson objectClass: kitnEduPerson kitnEduPersonRegId: SD00125 cn: Barton, Tom sn: Barton description: Professor, Mathematics uid: tbarton
