Exclude/Hide a user from GDM Logon Window

In Fedora 13, you can hide all users from the user list and simply login with a "Username:" prompt by altering this portion of /etc/gdm/gdm.schemas from true to false; this is essentially equivalent to clicking "Other" in the user list, and while it may not look ideal, it at least functions as it should.

Code:

<schema>
      <key>greeter/IncludeAll</key>
      <signature>b</signature>
      <default>true</default>
    </schema>

to

Code:

<schema>
      <key>greeter/IncludeAll</key>
      <signature>b</signature>
      <default>false</default>
    </schema>

or

gdm.schemas is not a configuration file and should not be treated as such. Edit /etc/gdm/custom.conf to accomplish what you need.

While the original thread was discussing how to hide individual users, here is how to hide all users from being displayed using /etc/gdm/custom.conf:

Code:

[greeter]
IncludeAll=false

Set to a list of users to always exclude in the Face Browser. This value is set to a list of users separated by commas. Note that the setting in the custom.conf overrides the default value, so if you wish to add additional users to the list, then you need to set the value to the default value with additional users appended to the list.
