Installation guide

lu ci for the first time.

As of Red Hat Enterprise Linux 6.4, the root user or a user who has been granted lu ci

administrator permissions can also use the lu ci interface to delete users from the lu ci interface,

which resets any permissions you have configured for that user.

Note

You can modify the way in which lu ci performs authentication by editing the

/etc/pam. d /l uci file on the system. For information on using Linux-PAM, see the pam(8)

man page.

To add users, delete users, or set the user permissions, log in to lu ci as ro o t or as a user who has

previously been granted administrator permissions and click the Ad min selection in the upper right

corner of the lu ci screen. This brings up the Users an d Permissio n s page, which displays the

existing users.

To add a user to the lu ci interface, click on Ad d a User and enter the name of the user to add. You

can then set permissions for that user, although you will still need to set up a password for that user.

To delete users from the lu ci interface, resetting any permissions you have configured for that user,

select the user or users and click on D el ete Sel ected.

To set or change permissions for a user, select the user from the dropdown menu under User

Permissio n s. This allows you to set the following permissions:

Luci Ad mi ni strato r

Grants the user the same permissions as the root user, with full permissions on all clusters

and the ability to set or remove permissions on all other users except root, whose

permissions cannot be restricted.

For each cluster that has been created or imported to lu ci, you can set the following permissions for

the indicated user:
