Implementing a secondary authentication scheme in
I have an apex application that authenticates using LDAP which would also check to see if a certain value in the database is true or false. I can't see how I can combine authentications.
You cannot combine the "pre-configured" schemes provided in APEX. However you could create a custom authentication scheme that combined LDAP authentication with your other check. This would need to be manually coded, it could not include the "pre-configured" LDAP functionality. I don't have any experience of using LDAP authentication so cannot help further.
