Grouper Users - Open Discussion List

[Jeffrey Williams <>]

Out of curiosity, for those who have implemented bushy provisioning to AD, has there been an issue afterwards with exceeding the 64 char limit for CN, OU names?

After three years, we just hit this the first time last week! Solved it by renaming and trimming folder and group names, as it hadn't gone live yet.

And the kludge gets complicated… ain't it funny how these patterns repeat?

Gabor - not saying what you suggest is wrong.  just observing.

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.

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.
