FreeIPA self-service account management tool
What is mokey?
mokey is web application that provides self-service user account management tools for FreeIPA. The motivation for this project was to implement the self-service account creation and password reset functionality missing in FreeIPA. This feature is not provided by default in FreeIPA, see here for more info and the rationale behind this decision. mokey is not a FreeIPA plugin but a complete standalone application that uses the FreeIPA JSON API. mokey requires no changes to the underlying LDAP schema and uses a MariaDB database to store access tokens. The user experience and web interface can be customized to fit the requirements of an organization's look and feel. mokey is written in Go and released under a modified BSD license.
mokey should be considered alpha software and used at your own risk. There are inherent security risks in providing features like self-service password resets and can make your systems vulnerable to abuse.
- Account Signup
- Forgot/Change Password
- Add/Remove SSH Public Keys
- Add/Remove TOTP Tokens
- Enable/Disable Two-Factor Authentication
- Hydra Consent/Login Endpoint for OAuth/OpenID Connect
- Easy to install and configure (requires no FreeIPA/LDAP schema changes)
- FreeIPA v4.5.0
- Linux x86_64
- Redis (optional)
- Hydra v1.0.0 (optional)
Note: mokey needs to be installed on a machine already enrolled in FreeIPA. It's also recommended to have the ipa-admintools package installed. Enrolling a host in FreeIPA is outside the scope of this document.
To install mokey download a copy of the pre-compiled binary here.
$ tar xvzf mokey-VERSION-linux-x86_64.tar.gz
deb, rpm packages:
$ sudo dpkg -i mokey_VERSION_amd64.deb $ sudo rpm -ivh mokey-VERSION-amd64.rpm
Setup and configuration
Create a user account and role in FreeIPA with the "Modify users and Reset passwords" privilege. This user account will be used by the mokey application to reset users passwords. The "Modify Users" permission also needs to have the "ipauserauthtype" enabled. Run the following commands (requires ipa-admintools to be installed):
$ mkdir /etc/mokey/private $ kinit adminuser $ ipa role-add 'Mokey User Manager' --desc='Mokey User management' $ ipa role-add-privilege 'Mokey User Manager' --privilege='User Administrators' $ ipa user-add mokeyapp --first Mokey --last App $ ipa role-add-member 'Mokey User Manager' --users=mokeyapp $ ipa permission-mod 'System: Modify Users' --includedattrs=ipauserauthtype $ ipa-getkeytab -s [your.ipa-master.server] -p mokeyapp -k /etc/mokey/private/mokeyapp.keytab $ chmod 640 /etc/mokey/private/mokeyapp.keytab $ chgrp mokey /etc/mokey/private/mokeyapp.keytab
Edit mokey configuration file and set path to keytab file, optionally set secrets and any other site specific config options:
$ vim /etc/mokey/mokey.toml # Path to keytab file keytab = "/etc/mokey/private/mokeyapp.keytab" # Secret key for branca tokens. Must be 32 bytes. To generate run: # openssl rand -hex 32 token_secret = "" # CSRF token secret key. Should be a random string csrf_secret = ""
It's highly recommended to run mokey using HTTPS. You'll need an SSL cert/private_key either using FreeIPA's PKI, self-signed, or from a commercial certificate authority. Creating SSL certs is outside the scope of this document. You can also run mokey behind haproxy or Apache/Nginx.
Start mokey service:
$ systemctl restart mokey $ systemctl enable mokey
SSH Public Key Management
mokey allows users to add/remove ssh public keys. Servers that are enrolled in FreeIPA can be configured to have sshd lookup users public keys in LDAP by adding the following lines in /etc/ssh/sshd_config and restarting sshd::
AuthorizedKeysCommand /usr/bin/sss_ssh_authorizedkeys AuthorizedKeysCommandUser nobody
Hydra Consent and Login Endpoint for OAuth/OpenID Connect
mokey implements the login/consent flow for handling challenge requests from Hydra. This serves as the bridge between Hydra and FreeIPA identity provider. For more information on Hydra and the login/consent flow see here.
To configure the Hydra login/consent flow set the following variables in
[hydra] admin_url = "http://127.0.0.1:4445" login_timeout = 86400 fake_tls_termination = true
Any OAuth clients configured in Hydra will be authenticated via mokey using FreeIPA as the identity provider. For an example OAuth 2.0/OIDC client application see here.
