I integrated our CMA 5000 to Active Directory; however, the Display Name in AD has an exclamation mark (!) in the name. This was preventing our endpoints from searching for these rooms in the Directory. I'm wondering if there's some official documentation on what special characters are restricted? Speaking with a tech they pointed out having issues with a period, but I seem to have no issues with hyphens or underscores!
Also, when an endpoint, such as an HDX, does a search in the directory, what field in AD does it query? Is it the User objects "display name", AD name, first name, last name?
