We have an eDir attribute called:

businessCategory

When I go into [This] in iMangler 2.6 to give it property rights to that
attribute, it doesn't show up in the list.

Even if I check the "show all properties" in Schema.

The only "b" categories that show up are all:

BRDSRV

They show up in ConsoleOne, DAL, etc.

Any ideas?

Also, if I want to let people view certain attributes on OTHER users, do
I also assign those to the "This" object as well (with a READ right)?

Like all users should be able to see what other people's managers are
and things like that.
