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. For screenshots see here
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.

Update to latest rpm release:
$ rpm -Uvh mokey-0.x.x-x.el7.centos.x86_64.rpm
If upgrading from v0.0.5 or earlier need to run the following command to update database schema:
$ mysql -u root -p mokey < /usr/share/mokey/ddl/upgrade-to-v0.0.6.sql
WARNING Security questions have been removed in v0.5.1 and are no longer supported. Please consider using TOTP tokens in FreeIPA for Two-Factor authentication.
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. These docs also assume you're running CentOS 7.x
Install the RPM release here:
$ rpm -Uvh mokey-0.x.x-x.el7.centos.x86_64.rpm
Install MariaDB and/or setup database for mokey:
$ yum install mariadb-server $ systemctl restart mariadb $ systemctl enable mariadb $ mysql_secure_installation $ Root Password: [Create a good, strong password here] $ Remove anonymous users? [Y/n] y $ Disallow root login remotely? [Y/n] y $ Remove test database and access to it? [Y/n] y $ Reload privilege tables now? [Y/n] y $ mysql -u root -p $ mysql> create database mokey; $ mysql> grant all on mokey.* to [user]@localhost identified by '[pass]' $ mysql> exit $ mysql -u root -p mokey < /usr/share/mokey/ddl/schema.sql
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/keytab $ 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/keytab/mokeyapp.keytab $ chmod 640 /etc/mokey/keytab/mokeyapp.keytab $ chgrp mokey /etc/mokey/keytab/mokeyapp.keytab
Edit mokey configuration file. Add user/pass for MariaDB database, path to keytab, auth and encryption keys:
$ vim /etc/mokey/mokey.yaml dsn: "user:pass@/dbname?parseTime=true" keytab: "/etc/mokey/keytab/mokeyapp.keytab" ktuser: "mokeyapp" auth_key: "32 or 64 bytes random key" enc_key: "16, 24, or 32 byte random key" [ edit to taste ]
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.
Copy your SSL cert/private_key to the following directories and set correct
paths in /etc/mokey/mokey.yaml. The mokey binary will run as non-root user
(mokey) so need to ensure file perms are set correctly:
$ mkdir /etc/mokey/{cert,private}
$ cp my.crt /etc/mokey/cert/my.crt
$ cp my.key /etc/mokey/private/my.key
$ chmod 640 /etc/mokey/private/my.key
$ chgrp mokey /etc/mokey/private/my.key
Start mokey service:
$ systemctl restart mokey $ systemctl enable mokey
Open a web browser to: https://localhost:8080. By default, mokey will listen on port 8080.
To view mokey system logs run:
$ journalctl -u mokey
The templates for the web interface and emails are installed by default in /usr/share/mokey/templates. Edit to taste and restart mokey.
mokey can be configured to send PGP/Mime signed email messages. First generate a gpg keypair:
$ gpg --gen-key $ gpg --armor --output example-key.gpg --export-secret-keys example@example.edu $ gpg --armor --output example-pub.gpg --export example@example.edu $ mkdir /etc/mokey/gpg $ cp example-key.gpg /etc/mokey/gpg $ chmod 640 /etc/mokey/gpg/example-key.gpg $ chgrp mokey /etc/mokey/gpg/example-key.gpg
Next, edit /etc/mokey/mokey.yaml:
$ vi /etc/mokey/mokey.yaml pgp_sign: true pgp_key: "/etc/mokey/gpg/example-key.gpg" pgp_passphrase: "my-secret" $ systemctl restart mokey
Publish your public key to a keyserver or other means. Emails will now be PGP signed using your private key. Users can verify the authenticity of the emails sent from mokey using your public key.
mokey can optionally be configured to rate limit certain paths (login and
forgot password) to limit the number of requests within a given time period. To
enable rate limiting first install redis then update /etc/mokey/mokey.yaml.
Install Redis (install from EPEL):
$ yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm $ yum install redis $ systemctl restart redis $ systemctl enable redis
Edit /etc/mokey/mokey.yaml and restart:
$ vi /etc/mokey/mokey.yaml rate_limit: true $ systemctl restart mokey
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
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
/etc/mokey/mokey.yaml:
hydra_admin_url: "https://localhost:4444"
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.
First, you will need Go v1.13 or greater. Clone the repository:
$ git clone https://github.com/ubccr/mokey $ cd mokey $ go build .
