The requirement is to add an authorization policy for permissions (containing Roles + LDAP Groups) for a resource against an action. I have exported the policy XML from the OES using policyIX.sh and tried updating the authorization policy. The ATZ policy XML block will be as shown below:<\/p>\n

<xb:authorization_policy_entry>
\n<xb:policy_effect value=”grant”\/>
\n<xb:policy_actions>
\n<xb:policy_action_entry value=”MyAction”\/>
\n<\/xb:policy_actions>
\n<xb:policy_resources>
\n<xb:policy_resource_entry value=”\/\/resources\/MyApp\/MyResource”\/>
\n<\/xb:policy_resources>
\n<xb:policy_subjects><\/p>\n

<xb:policy_group_entry name=”Group1″ directory=”TMobileDir” scope=”RootOrg!TMobileOrg”\/>
\n<xb:policy_group_entry name=”Group2″ directory=”TMobileDir” scope=”RootOrg!TMobileOrg”\/>
\n<xb:policy_group_entry name=”Group3″ directory=”TMobileDir” scope=”RootOrg!TMobileOrg”\/>
\n<xb:policy_group_entry name=”Group4″ directory=”TMobileDir” scope=”RootOrg!TMobileOrg”\/>
\n…………………
\n…………………
\n<xb:policy_role_entry value=”Role1″\/>
\n<xb:policy_role_entry value=”Role2″\/>
\n…………………
\n…………………
\n<\/xb:policy_subjects>
\n<\/xb:authorization_policy_entry><\/p>\n

Please note that Groups should be placed first and then Roles in the Policy Subjects.<\/p>\n

I have tried importing XML using policyIX.sh and resulted with below error.<\/p>\n

Importing roles …<\/p>\n

all roles finished<\/p>\n

Importing policies …<\/p>\n

Policy Propagation is terminated<\/p>\n

failed to create application RootOrg!MyOrg!MyApp for<\/p>\n

\nROLE:Role40]) if true; for<\/p>\n

The subject field in a rule cannot be longer than 2000 characters.<\/p>\n

It is perhaps clear from the error that max size limit is 2000 characters for policy subject value. So I have calculated the characters using a tool and found it is around 2400 characters.<\/p>\n

So the next attempt is to include just the roles in policy Subjects and imported the policy and is through. So I have tried manually adding the Groups to the policy subjects using OES Admin console which resulted in below error.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

The next attempt is to create a new authorization policy with just adding Groups in Policy Subjects and then the import is succesful. So totally I have created two authorization policies for same set of actions and resources but seperated the policy subjects Roles and Groups into each other.<\/p>\n","protected":false},"excerpt":{"rendered":"
