I can successfully sign into the Flowable apps when using LDAP:
docker run -d --name flowable \
  -p 8080:8080 \
  --env-file ./ldap-env.txt \
  flowable/all-in-one:6.5.0
and when not using LDAP:
docker run -d --name flowable \
  -p 8080:8080 \
  --env-file ./no-ldap-env.txt \
  flowable/all-in-one:6.5.0

FLOWABLE_IDM_APP_ADMIN_USER_ID=flowable
FLOWABLE_IDM_APP_ADMIN_PASSWORD=test
FLOWABLE_IDM_APP_ADMIN_FIRST_NAME=Flowable
FLOWABLE_IDM_APP_ADMIN_LAST_NAME=Administrator
FLOWABLE_IDM_APP_ADMIN_EMAIL=admin@flowable.org
FLOWABLE_COMMON_APP_IDM_ADMIN_USER=flowable
FLOWABLE_COMMON_APP_IDM_ADMIN_PASSWORD=test
Note: If you don’t properly configure the default Administrator accounts you may be able to sign in to Flowable’s Identity Management application, however, you won’t be able to sign in to the other Flowable UI applications.
