Authetication in ScienceDirect and Scopus (Shibboleth)

We would like to inform the users that the log in to the ScienceDirect and Scopus via Shibboleth may fail. This is not happening always, however, it may occur from time to time (the log in process ends up with opensaml::FatalProfileException message). We are investigating the issue toghether with Elsevier (Scopus and ScienceDirect provider). We kindly ask users who encounter this issue to use alternative remote access method.
