As a Canadian, I find I try to use proper capitalization and punctuation whereever possible.
One place where this is a mistake is when naming an IDM Policy object - or any other object that is stored in eDirectory by its pretty name.
I like to use descriptive names for Policies and Rules, so they are somewhat self-explanatory.
[ACME] Rule to transform User Disables.
[ACME] Rule to transform User Disables..acmedriver.acme
You can see the double period in the object name, which will not work in eDirectory well.
Easy enough to fix - use incorrect punctuation!
