8.2. Fixing ID Conflicts
IdM uses ID ranges to avoid collisions of POSIX IDs from different domains. For details on ID ranges, see ID Ranges in the Linux Domain Identity, Authentication, and Policy Guide.
POSIX IDs in ID views do not use a special range type, because IdM must allow overlaps with other kinds of ID ranges. For example, AD users created through synchronization have POSIX IDs from the same ID range as IdM users.
POSIX IDs are managed manually in ID views on the IdM side. Therefore, if an ID collision occurs, fix it by changing the conflicting IDs.
