The issue you are facing:
LDAP user can successfully authenticate, upload and share files to other ldap, internal users and by share link. However when the ldap user logoff and if any one try to access the share file via public link following error appears in web page. The shared files are only accessible to anyone as long as the file owner is logged in. This happens after LDAP/AD Integration apps settings Cache-Time-To Live expires.
