====== Error statuses of authentication process ======

| \\  **Code**   | \\  **Brief description**   | \\  **Note**   |
| \\  **OK**   | \\ Success  | \\ Normal → normal success  |
| \\  **KO**   | \\ Failure  | \\ Normal → normal negative result  |
| \\  **NAU**   | \\ Disagreement at user side  | \\ Rejected by user - real or artificial because PEIG is temporarily blocked → normal authentication failure  |
| \\  **PPNP**   | \\ PEIG is not available  | \\ Functional problem - PEIG is not connected to PEIG-Proxy → Display to user (with instructions)  |
| \\  **USP**   | \\ Unknown service provider  | \\ Normal status - unknown user → management (initialization menu - init)  |
| \\  **USSP**   | \\ Unknown secondary service provider  | \\ Normal status - unknown user for secondary provider → management (explanatory text - link with other SP)  |
| \\  **UU**   | \\ Unknown user  | \\ Operating status or security problem - the identity obtained from PEIG does not exist in AIM → management - either it is an attack, or repair after AIM failure - reinit  |
| \\  **UUS**   | \\ Unknown user for secondary provider  | \\ Operation status or security problem - the identity does not exist in a secondary AIM → management - it is either the operation status, attack or repair after failure of AIM - init, or reinit at secondary AIM  |
| \\  **UI**   | \\ Invalid identification  | \\ Operation status - PEIG Operation status - PEIG or AIM determined that CyberID is violating terms of validity (time or number of uses) → management - e.g. rechange menu or change in access rights  |
| \\  **UPR**   | \\ Unsupported security profile  | \\ AIM or PEIG cannot find (accept) the requested security profile → change of profile or denial of PEIG  |
| \\  **UIP**   | \\ Unsupported IL security profile  | \\ AIM or PEIG cannot find (accept) the requested IL (identity link) security profile → change in IL profile or request denial  |
| \\  **UOP**   | \\ Unsupported extension object profile  | \\ PEIG cannot accept the required security profile of the extension object → change of profile or request denial  |
| \\  **VI**   | \\ Valid identity  | \\ Functional problem or security incident - CyberID is valid upon requirement for rechange → probable use of rechange  |
| \\  **NEO**   | \\ Non-existing extension object  | \\ Functional problem - request for non-existing object → probable application error  |
| \\  **NTD**   | \\ Nothing to do  | \\ Normal - nothing to apply the request to → normal behaviour - failure (e.g. reading an empty list of objects) - application error or normal operation status  |
| \\  **SPE**   | \\ Error of second PEIG  | \\ Security of functional problem - attack or operation status or user error  |
| \\  **UTL**   | \\ Unsupported transition between security levels  | \\ Cannot accept the required change in security profile → change of request or acceptance of unknown CyberID  |

| \\  **CTO**   | \\ Exceeded max. communication time  | \\ Functional problem → configuration error or operation problem  |
| \\  **ERR**   | \\ Unspecified error  | \\ Security of functional problem: attack or implementation error, standard, general error message instead of specific ones  |
| \\  **UV**   | \\ Unsupported version  | \\ Functional problem (incompatibility) → management - change of request  |
| \\  **DI**   | \\ Repeated initialization  | \\ Functional problem or security incident - PEIG identified an attempt at repeated origin of a CyberID for the same AIM → either an error in the application that did not check the existence of the CyberID, or a security attack or configuration error - another AIM exists with the same SPID  |
| \\  **CR**   | \\ Applying a rejected change  | \\ Recovery from problem - consequence  |
| \\  **MI**   | \\ Missing identity  | \\ Functional problem or security incident - CyberID does not exist upon request for reinit → probable incorrect use of reinit  |
| \\  **IE**   | \\ Self-termination  | \\ PEIG security compromised→ management of the compromise, e.g. flagging an attribute and blocking access rights  |
| \\  **NAP**   | \\ Not accepted by PEIG  | \\ Secondary error - use primary  |
