Dewberry users who login with ADFS may use the "My Settings" button - click the menu in the upper right hand corner of the page where your name is displayed and from the menu choose "My Settings". Dewberry users may want to update their profiles on each site and change their display name.
External users who login with a 3rd party identity provider may use the "My Settings (Live)" button on that same menu. Profiles for external users are synchronized across sites. Note that if an external user changes his email address, the new email address will have to be verified.
An external user who is experiencing "Access Denied" errors, should ensure that the email address in his profile matches the email address where he originally received the invitation to the site. See this document for more details.
