For automember rules is there any documentation about the regex library that is in use?

[Chris Cowan]

I created some rules, and they worked as expected, but there's no guidance that I can find of which metacharacters are supported.

Perhaps if I knew they were using the perl regex library, or whatever that might help.  Also, it seems like the inclusive rules are OR'ed together, but that is not discussed either.  I may not be looking in the right places for documentation.

So, far I have found that this worked as expected.
departmentnumber = ^(ABC|DEF|GHI)

And I was able to accomplish the same thing with 3 distinct rules.   Just wondering what flexibility, I have here.

This is handled in 389-ds. The regex is a thin wrapper around pcre.

The rules are not OR'd together. With three separate rules one matched
so it was applied.
