Determine permissions for example 3

User X is a member of group U3, U2, and U1.

User Y is a member of group U4, U2, and U1.

Target A is a member of group T4, T2, and T1.

Target B is a member of group T5, T2, and T1.

Session with user X and target A
The only permissions link that is considered for these two entities is the one between U1 and T1. User X is not a member of U4. Therefore, user X can start a Chat session with target A, but not a Monitor session.

Priority 1 No overrides priority 0 Yes.

Priority 1 Yes overrides priority 0 No.

Note: The standard permissions for group T2 have Chat set to priority 0 No. This value overrides standard Yes. However, because there is no permission link with T2 and any other group, its values are not considered. It is the policy values in permissions links only that are inherited.
Session with user X and target B
Only the link between U1 and T1 is considered. User X is not a member of U4 and target B is not a member of T4. Therefore, user X can start a Chat session with target B but not a Monitor session. The T2 permissions are not considered in this example.
Session with user Y and target A
There are 2 permissions links to be considered. U1 to T1 and U4 to T4. Therefore, user Y can start a Monitor session with target A. The priority 1 value in the link between U4 to T4 overrides the priority 0 value in the link between U1 and T1. Group T2 policies and permissions are not considered as there are no permissions links set up between it and any other groups.
Session with user Y and target B
The only permissions link that is considered for these 2 entities is the one between U1 and T1. Target B is not a member of T4. The value of priority 0 No in the standard set for T2 would override the U1 to T1 priority 0 Yes if T2 was linked to another group. As it is not, the value is not considered. Therefore, user Y can start a Chat session with target B, but not a Monitor session.
