The RBA plugin sends a reset when attempting to access a secondary authentication domain: /var/log/ltm: Internal error (APM::RBA requested abort (trans end error))


Multidomain SSO is effectively unusable, since you can only access the primary domain.


Any configuration of LTM+APM multidomain SSO seems to be affected. Forward proxy deployments, such as Secure Web Gateway, do not appear to be affected.


There is no workaround at this time. Single-domain authentication still works.

Fix Information

Multidomain SSO no longer resets on secondary authentication domains.
