User Credentials in a Security Enabled Model

If the model connected via Pro Cloud Server has User Security enabled, then you will have to validate the user credential before creating a Resource or Resource Feature. Once the user credential is validated, you will be provided with a User Security GUID that you will have to pass-in with the OSLC GET and POST Requests. Unless you pass-in the User Security GUID, the OSLC request on a Security Enabled model will not be processed by the Pro Cloud Server.

To get the User Security GUID:

  • POST the User credentials (User ID and Password) to a specific URL; these are the same credentials that you will type into the 'Login to EA Repository' dialog in a security-enabled model
  • Upon successful validation, the XML returned will contain the User Security GUID (amongst other information) in the XML element 'ss:useridentifier'

Validating User Credentials in a Security Enabled Model

Step

Action

1

Validate the User by POSTing to:

     URL: <protocol>://<server>/<model_name>/oslc/am/login/

     POST Body: uid=<USER ID>;pwd=<PASSWORD>

2

If user validation succeeds, the response will typically be:

Passing User Security GUID with OSLC Requests

Once the User Credential is successfully validated, you pass in the User Security GUID in every OSLC request; that is, pass-in the User Security GUID:

  • When retrieving a Resource or Resource Feature XML using GET Request as the value of the query string parameter 'useridentifier'
  • When creating/updating a Resource or Resource Feature using POST RDF/XML as the value of the XML element 'ss:useridentifier'

Passing User Security GUID with GET Requests

For GET requests, pass-in the User Security GUID as the value of the query string parameter 'useridentifier':

  • <protocol>://<server>/<model_name>/oslc/am/OSLC REQUEST/?useridentifier=<USER GUID>

Examples

No.

Example

1

Retrieve the Properties of an Enterprise Architect Package Resource:

  • Whose GUID is {5147E138-1F14-4738-B721-5FCC0F8821A8}
  • In a Security Enabled model
  • Where the User Security GUID is {72825AF9-E116-48f1-9DF8-77815E66B1A7}

http://localhost:480/firebird_model/oslc/am/resource/pk_{5147E138-1F14-4738-B721-5FCC0F8821A8}/?useridentifier={72825AF9-E116-48f1-9DF8-77815E66B1A7}

2

Retrieve all Resources:

  • With the name Class1
  • In a Security Enabled model
  • Where the User Security GUID is {72825AF9-E116-48f1-9DF8-77815E66B1A7}

http://localhost:480/firebird_model/oslc/am/qc/?useridentifier={72825AF9-E116-48f1-9DF8-77815E66B1A7}&oslc.where=dcterms:title="Class1"

Passing in a User Security GUID with OSLC POST Requests

For OSLC POST requests, you need to pass-in the User Security GUID as a part of the RDF/XML accompanying the POST request.

Examples

No.

Example

1

In a Security Enabled model where the User Security GUID is {72825AF9-E116-48f1-9DF8-77815E66B1A7}, a Class 'Class1' is created under a Package with the Enterprise Architect GUID {965A54C2-6A89-46d7-AB7E-F192668010CA}. The Notes, Complexity and Version are set.

2

In a Security Enabled model with the User Security GUID {72825AF9-E116-48f1-9DF8-77815E66B1A7}, an Actor 'Actor1' with the Enterprise Architect GUID {567854C2-6A89-46d7-AB7E-F192668010CA} has its name updated to 'Actor 1_New'.

Notes

  • This facility is available through the Enterprise Architect Pro Cloud Server
  • An OSLC request will not be processed by the Pro Cloud Server unless the User Security GUID is passed-in with the OSLC request on a Security Enabled model
  • 30 minutes of inactivity will log you out of a Security Enabled model; you will have to login again by POSTing the User Credentials to the credential validation URL
