Purpose and scope

eduroam CAT

eduroam CAT is the eduroam Configuration Assistant Tool. Its purpose is to allow authorised eduroam Identity Providers to generate customised eduroam installers for their institution's RADIUS setup on many platforms. It also allows them to test and debug their RADIUS setup. Authorisation for IdPs to use eduroam CAT is determined by the eduroam National Roaming Operator (NRO, a.k.a. the eduroam "federation").

An NRO administrator accredits new eduroam IdPs, changes IdP details, or deprovisions eduroam IdPs. The primary vehicle for this is not eduroam CAT, but the official eduroam database, which contains all registered IdPs and their contact details.


The web presence of eduroam Managed IdP is

Terms of use

eduroam NRO has the full authority to decide and invite the IdPs from NRO's constituency to use eduroam CAT and Managed IdP supporting tools.

For the eduroam Managed IdP tool, there is a limit of a maximum number of 10.000 active end users per NRO. Should the number of active end users within an NRO's constituency exceed this number, eduroam Operations team will contact respective NRO to determine further steps. That limit is not technically enforced and can be followed up with delay and asynchronously. So, no online notification in any way is foreseen.


The NRO administrator interface of eduroam CAT and eduroam Managed IdP are largely identical. The remainder of this document will refer to both as "the toolset".


For users with the NRO management privilege, the toolset provides a dedicated web interface which allows them to

  • invite a new IdP to use eduroam CATthe toolset
  • add new representatives to existing IdPs
  • delete representatives of existing IdPs
  • take control over an IdP
  • manage the relationship between an IdP in the toolset vs. an IdP in the official eduroam database


The button on the lower end of the page allows you to send an invitation to use the toolset to an IdP in your federationNRO. This can either be an IdP which is already in production (i.e. already listed in the official eduroam database with at least the "IdP" role) or it can be a new institution which is still in a bootstrapping phase (i.e. not yet registered in the official eduroam database). eduroam Managed IdP institutions are not typically registered, because their realm is not determined yet - it will be set by the eduroam Managed IdP system.


Once an IdP exists in in the toolset (i.e. once the first invitation token for the IdP has been redeemed by an invitee), the IdP admin can add more administrators or delete others as he sees fit. You can do the same though, by using the "Add/Remove Administrators" link on the right side of the list of IdPs. Please consult the IdP-level guides to the respective tool of the toolset for further details of administrator management, available here for CAT and here for Managed IdP.

Take control over an IdP


Manage the relationship between an IdP in eduroam CAT vs. an IdP in the official eduroam database

Since the official eduroa eduroam database contains only production-level eduroam IdPs, but the CAT can also be made available to IdPs which are still in a setup/bootstrap phase, the databases of the tools are not in perfect sync. To avoid fragmentation and desynchronisation of the databases, NRO administrators are encouraged to link the same IdP in both databases together.


As a NRO administrator, depending on the number of IdPs in your federationNRO, you may find it cumbersome to add IdPs interactively. Or maybe you already have a customer self-service management system where authorised IdP admins could self-enroll without you being in the middle.

For cases like this, a small API was created which allows federation NRO administrators to automate a limited amount of actions:

  • Creation of a new IdP
  • Creation of a new Profile for an IdP
  • Listing and Adding administrtators administrators of an IdP
  • For eduroam Managed IdP, managing user populations inside IdP profiles


The CAT Admin API requires the NRO admin to be in possession of an API key. The API key is a long random string which needs to be used when executing API actions. The key is also bound to the federationNRO; i.e. you can only create or query IdPs in your own federation NRO with it.

API keys are distributed from the eduroam Operations Team to NRO administrators on email request. Please contact eduroam Operations for your Admin API key; API keys from version 1.x continue to be valid for version 2.0.


The authoritative reference for the list of ACTIONs is on GitHub, : the class constants API::ACTION_* are the available strings to put into the JSON ACTION field.


The authoritative reference for the list of PARAMETERs is on GitHub, : the class constant API::ACTIONS contains two sets of parameters each, "REQ" = required parameters, "OPT" = optional parameters,

All parameters with potentially binary value are to be sent base64-encoded. That's also true for PEM files.

If the parameter is the integer representation of an EAP type, you can look up the number to use in the source (const INTEGER_...).

List of result codes

The HTTP POST will be answered with a "result" field, which is either "SUCCESS" or "ERROR". It is accompanied by a "details" field, which contains either the response details, or in the case of error, an additional "errorcode" and "description". The auhoritative

The content of the response details is given in the constant API::ACTIONS along with the list of parameters (see above) as "RETVAL".
