We have flows that send out emails with buttons, so users can approve/reject without logging on to Lawson. Has been working for many years.
Recently, the site changed their authentication from SAM to UPN. This seems to have broken something. Users are now forced to login to Lawson to take action.
The system property "emailActionAuthenticationRequired" was not there. tried creating it and setting it to true/false. No effect.
One theory floated is that the email server still uses SAM authentication whereas Lawson now uses UPN. Is there someplace the two need to be sync'ed?
Can anybody give any pointers on where to go from here? Thanks.
