When I export a user I find values like: <department></department> <domain_entry_id>39323336363566612D373333622D346532612D396530632D316630396536643634636432</domain_entry_id> <email></email> <last_name></last_name> <name>admin</name> <namespace>*</namespace> <principal>admin</principal> <user_name>admin@internal-authz</user_name> <domain href="/ovirt-engine/api/domains/696E7465726E616C2D617574687A" id="696E7465726E616C2D617574687A"> <name>internal-authz</name> </domain> <permissions href="/ovirt-engine/api/users/0000001a-001a-001a-001a-0000000003b4/permissions"/> <roles href="/ovirt-engine/api/users/0000001a-001a-001a-001a-0000000003b4/roles"/> <ssh_public_keys href="/ovirt-engine/api/users/0000001a-001a-001a-001a-0000000003b4/sshpublickeys"/> <tags href="/ovirt-engine/api/users/0000001a-001a-001a-001a-0000000003b4/tags"/> They are the same that one defined from the type in sdk (http://ovirt.github.io/ovirt-engine-sdk/master/types.m.html#ovirtsdk4.typ...). If I look in http://www.ovirt.org/documentation/admin-guide/appe-Using_Search_Bookmark..., I see fields like pool, group that I don't map to fields in the type. In the search bar in the UI, I also see fields like login, directory or type. The mapping is less obvious, even if I can guess that login maps to principal. But I wonder why such name discrepancy exists and if they are documented somewhere.
