Basic web app that allows a user to generate a JSON Web Token (JWT) authenticating against a LDAP server.
End user usage:
curl -H "Content-Type: application/json" \
-X POST -d '{"username": "olssont", "password": "secret" }' \
http://localhost:5000/token
Token consumer usage:
curl http://localhost:5000/public_key
Installation:
git clone REPO cd REPO pip3 install -r requirements
Configuration:
export FLASK_APP=app.py export FLASK_CONFIG_FILE=production.cfg export JWT_PUBLIC_KEY_FILE=~/.ssh/id_rsa.pub export JWT_PRIVATE_KEY_FILE=~/.ssh/id_rsa
Optionally, the expiration time can changed from the default setting of 15 seconds, in the example below it is extended to two days:
export JWT_ACCESS_TOKEN_EXPIRES=2880
Create a file named production.cfg with contents along the lines of the
below to allow the server to pass on the authentication of users to an external
LDAP server:
LDAP_HOST="ldap://ldap.famousuni.ac.uk" LDAP_BASE_DN="ou=users,dc=famousuni,dc=ac,dc=uk" LDAP_USER_OBJECT_FILTER="(objectclass=person)" LDAP_SEARCH_FOR_GROUPS=False LDAP_USER_SEARCH_SCOPE="SUBTREE" LDAP_USER_LOGIN_ATTR="UID" LDAP_BIND_USER_DN="" LDAP_BIND_USER_PASSWORD=""
See flask-ldap3-login documentation for more information on how to configure the connection to the LDAP server.
Starting the server:
flask run
Utility commands:
flask generate-token <username> flask test-authentication <username>
