Grouper Users - Open Discussion List

["Eszes, Gabor" <>]

We use a similar trick. After considering all the requirements (length limit, 
maintaining human readability, content-based deterministic output, avoiding 
dependence on stateful counter), other solutions fall away and the hash 
suffix remains. It'd be worth including a util function that can generate 
names of this variety, with some sensible defaults, and configurability for 
those who need it. Params for max length, separator char, suffix length, 
possibly params for hash and hash encoding.

Subject: Re: [grouper-users] pspng to AD error

Seeking consensus of something goofy we do with our AD groups at GT...

If the CN exceeds 64 characters, we make the cn the first 59 chapters 
followed by a dash and then a few characters of the hex hash the entire 
value. In the last 12 years, no one has complained because the first 59 
characters is generally enough [1] to tell what the group is and the 
description is complete.

[1] - We reverse the group path in the cn so the most important parts are 
first.


I haven’t standardized this in PSPNG because it is so kludgey, but I can 
create a util function easily enough.

What do people think?
