tab, accessible by
right-clicking Users or
Groups or Computers

does not show the
actual rule being
applied to the user,
group or computer.
You may not have been granted read
permission for the rule which is actually
being applied to the user, group or
computer. In which case the rule will not be
listed for you.
It is important that network administrators
responsible for resolving network access
problems are given read access on all rules
created in 3Com Network Access Manager.
Ask the network administrator who
created the rules in 3Com Network Access
Manager to grant you read permission for
all rules.

Either:
The VLAN ID applied to the rule associated
with the user may not match the VLAN ID
in the network access device that the user
connects to.
Or:
The authentication mode enabled on the
network access device may be incompatible
with the settings on the Action tab for the
rule associated with the user, group or
computer.
Ensure the VLAN ID set for the rule,
matches the ID assigned to the VLAN in
the network access device. Refer to the
user documentation shipped with the
network access device for information on
determining the VLAN ID assigned in the
network access device.
Ensure the authentication mode selected
on the network access device matches
how the rule has been setup. Either
change the rule setting or else select a
different authentication mode on the
network access device.
