Cannot login in seafile client after migration to seafile pro 7.1.3

[vmakarenko]

Found a regression for institution middleware: Setup as described in https://download.seafile.com/published/seafile-manual/deploy_pro/multi_institutions.md seahub_settings.py related settings are: MULTI_INSTITUTION = True EXTRA_MIDDLEWARE_CLASSES = (
'seahub.institutions.middleware.InstitutionMiddleware', 'shibboleth.middleware.ShibbolethRemoteUserMiddleware',
'seahub_extra.organizations.middleware.RedirectMiddleware', )

With the settings Seafile Client (7.0.6, Ubuntu) cannot login anymore:
