Because, SLO could be handled only by the protocol endpoints (servlets), not by a common point like Authentication Framework. And each protocol might have a set of SLO related rules/procedures which are known and handled only by that protocol, thus cannot be handled by the authentication framework. E.g. Issuance and maintenance of SessionIndex in SAML SLO. So taking the example you have mentioned, we are talking about initiating a SLO request from the OAuth2/OpenIDConnect servlet upon a SAML logout request. (Please note that I'm not familiar with the OIDC Session Management spec, so I'm assuming SLO is in it and IS will have it in near future) We might have to further brainstorm on this. > > PS : seen following jira[1] which also related. > > [1] https://wso2.org/jira/browse/IDENTITY-2643 > > Thanks, > Darshana > -- > Regards, > > > *Darshana Gunawardana*Software Engineer > WSO2 Inc.; http://wso2.com > > *E-mail: darsh...@wso2.com <darsh...@wso2.com>* > *Mobile: +94718566859 <%2B94718566859>*Lean .
