Certain operations such as backup generation previous to an upgrade or migration require "freezing" the content to ensure data are not lost. Currently, the alternatives are:
Shutting down the system: this makes new data generation impossible, but makes the sites completely unavailable.
Disabling login (e.g. through ENV variable LIFERAY_AUTH_PERIOD_LOGIN_PERIOD_DISABLED=true or its equivalent portal property): this prevents access from regular login, but login via SAML or content creation via API is still possible.
See PTR-2279 for further discussion.
- Given the LIFERAY_AUTH_PERIOD_LOGIN_PERIOD_DISABLED (or its corresponding portal property) is set to true, then:
- login via UI is disabled (current behavior)
- authenticated API operations are disabled (new behavior).
- login via SSO (e.g., with SAML) is disabled (new behavior)
