Drinks in AD

Today, I got the hint to take a deeper look into the AD. Surprisingly I found the following entry in the Active Directory Schema:

drink Attribute

Sounds like a joke, doesn’t it? If you have a look into RFC 1274 search for section 9.3.5. There you will find

9.3.5. Favourite Drink

The Favourite Drink attribute type specifies the favourite drink of
an object (or person).

favouriteDrink ATTRIBUTE
(SIZE (1 .. ub-favourite-drink))
::= {pilotAttributeType 5}

Seems like it is no joke at all…
