Click Close to close dialog
The webservices_rest version is aligned with the DX UIM version. It can be found in the "Installed Packages" button of the controller probe.
The webservices_rest version can also be viewed at this endpoint:
http://<IP or hostname of OC>:<port>/rest/version-info
Environment
DX NetOps Spectrum: Any version
DX Unified Infrastructure Management (UIM): Any version
Cause
The cause of this issue is the permission issue (ACL) of the user used for the connection validation. The user must have the "web service" ACL enabled for the webservices_rest.
http://<IP or hostname of OC>:<port>/rest/origins
Where OC is the Operator Console
Insufficient permission for operation - permission required: Web Service

Resolution
Open Infrastructure Manager:
> go to: Security
> "Manage Access Control List..."
> and select the ACL assigned to the affected user
> Enable the "Web Service" ACL
■ If the 'Web Service' ACL is not avaialable at all, even for the superuser ACL, the security.cfg ACL list may be corrupt. In this case, follow the below procedure:
1. Open Infrastructure Manager
2. Navigate distsrv probe on the primary UIM server.
3. With the distsrv probe highlighted, press "Ctrl-P" the probe Utility (pu) should appear.
4. In the probe commandset, select callback set_init_acl with the parameter value "base_acls.cfg".
The callback updates the security.cfg with default ACLs.
