   Notes:
    1. Sun Ray Server Software 1.x is not affected by this issue.
    2. Sun Ray Server Software 2.0 is not supported on Solaris 10 or for
       the x86 Platform.
    3. Sun Ray Server Software 3.0 is not supported on the Solaris x86
       platform. (3.1 only)
    4. Sun Ray Server Software 3.1 is not supported for Solaris 8 and 9
       on the x86 platform. (Solaris 10 only)

   To determine the version of Sun Ray Server Software on a system, the
   following command can be run:
    # /usr/bin/pkginfo -l SUNWuto | grep -i version
    VERSION:  3.1_32,REV=2005.08.24.08.55

   To determine if the utxconfig(1) utility has been installed as part of
   the Sun Ray server software, the following command can be run:
    $ pkginfo SUNWuta

3. Symptoms

   There are no symptoms that would indicate the described issue has
   occurred. 

4. Relief/Workaround

   bit from the utxconfig(1) command until the patch can be applied. To
   apply this change, the following command can be run:
