When Iooking at "Security", "Logins" in Enterprise manager there are some accounts with Server Access configured as "Via group membership". If looking at the properties of this user there is an option under 'Authentication' which indeed states: "Through group membership".
What does option mean? Which groups is this setting referring to? How do I configure this/where is the current group membership arranged? Googling for this option did not give me the wanted information and/or explaination. Any info on this setting is welcome, the more the better!
