Local LDAP Linux User Accounts
|
|
==============================
|
|
|
|
You can manage regular Linux \(shadow\) user accounts on any host in the
|
|
cluster using standard Linux commands.
|
|
|
|
|
|
.. _local-and-ldap-linux-user-accounts-ul-zrv-zwf-mmb:
|
|
|
|
Local Linux user accounts should NOT be configured, only use local LDAP
|
|
accounts for internal system purposes that would usually not be created by
|
|
an end-user.
|
|
|
|
Password changes are not enforced automatically on the first login, and
|
|
they are not propagated by the system \(only for 'sysadmin'\).
|
|
|
|
.. note::
|
|
If the administrator wants to provision additional access to the
|
|
system, it is better to configure local LDAP Linux accounts.
|
|
|
|
|
|
- LDAP accounts are centrally managed; changes made on any host are
|
|
propagated automatically to all hosts on the cluster.
|
|
|
|
- LDAP user accounts behave as any local user account. They can be added
|
|
to the sudoers list and can acquire OpenStack administration credentials.
|
|
|
|
- The initial password must be changed immediately upon the first login.
|
|
|
|
- Login sessions are logged out automatically after about 15 minutes of
|
|
inactivity.
|
|
|
|
- The accounts block following five consecutive unsuccessful login
|
|
attempts. They unblock automatically after a period of about five minutes.
|
|
|
|
- All authentication attempts are recorded on the file /var/log/auth.log
|
|
of the target host.
|
|
|
|
|
|
|
|
.. note::
|
|
For security reasons, it is recommended that ONLY admin level users
|
|
be allowed to SSH to the nodes of |prod|. Non-admin level users
|
|
should strictly use remote CLIs or remote web GUIs.
|
|
|
|
Operational complexity:
|
|
|
|
.. _local-and-ldap-linux-user-accounts-ul-bsv-zwf-mmb:
|
|
|
|
- Passwords aging is automatically configured.
|
|
|
|
- LDAP user accounts \(operator, admin\) are available by default on
|
|
newly deployed hosts. For increased security, the admin and operator
|
|
accounts must be used from the console ports of the hosts; no SSH access is
|
|
allowed.
|
|
|
|
- |prod| includes a script for creating LDAP Linux accounts with built-in
|
|
Keystone user support. It provides an interactive method for setting up
|
|
LDAP Linux user accounts with access to OpenStack commands. You can assign
|
|
a limited shell or a bash shell.
