Proxy certificate API

IAM provides a RESTful API that can be used to download the X.509 proxy certificate previously uploaded in IAM dashboard by the user.
This is a plain proxy obtained by running voms-proxy-init command.

The API has been added mainly for the integration of IAM with the RCAuth.eu online certificate authority. The X.509 proxy certificate can be uploaded using the IAM Account Proxy Certificate API.

The proxy:generate OAuth scope is required to access this API.
Note that this scope is restricted in the default IAM configuration, i.e. can be assigned to clients only by IAM administrators.

POST /iam/proxycert

Returns a JSON representation of the proxy certificate of the user.

curl -s -X POST -H "Authorization: Bearer ${BT}" \
  -d client_id=${CLIENT_ID} \
  -d client_secret=${CLIENT_SECRET} \
  -d lifetimeSecs=${PROXY_CERT_LIFETIME_SECS} \
  http://localhost:8080/iam/proxycert

The user can request a specific lifetime of the proxy that is less than or equal to the maximum lifetime of the proxy itself and also limited by IAM configuration options max-ac-lifetime-in-seconds (as shown in VOMS AA configuration).

IAM response:
