[keycloak-dev] Offline Session Max for Offline Token

[乗松隆志 / NORIMATSU，TAKASHI]

Hello,

I've found that keycloak does not support Offline Session Max related to Offline Token while supports SSO Session Max related to Refresh Token.

For authorization of REST API services, long life(not infinite, such as 60days) refresh token is required, offline access and persistency in keycloak side are also expected. 
Therefore, Offline Session Max is required for offline token.

For example, consulting MS Azure, it has already supported this concept.
https://docs.microsoft.com/en-US/azure/active-directory/develop/active-directory-token-and-claims#token-revocation

I would like to try to implement this feature.
Best regards,
