Good Afternoon.
Possibly, you need to add the web services access privileges, to the user's role.
By default, only the Certificate user and users with the service provider (SP) administrator role can execute web services.
1) Login to the 'CA Service Catalog' application instance in EEM
2) Select 'Manage Access Policies' tab
3a) Confirm 'Guinode' is selected
3b) Search for 'ACL_requestmanager_Guinodes' policy
> Enter in the 'Name' field and click Go
4) Open the policy in which you would like to allow web services access
(i.e. ACL_requestmanager_Guinodes for Request Manager role in catalog)
or
(i.e. ACL_catalogenduser_Guinodes for Catalog User role in catalog)
5) Under 'Add resource' enter 'webservice__all' and select the plus icon
6) Save your changes.
7) Recycle the 'catalog service'
Possibly, for your environment, in stead of 'ACL_catalogenduser', look for 'ACL_requestmanager'
So, first click on 'USM_Resource' under 'Accesss Policies'.
Then, in 'Show policies matching name' enter ACL_requestmanager in the Name: and click Go.
Open this policy and add the resource as named in the document.
