Aus der Admin Hilfe:
Enter a name for the group, using any of these characters: A - Z, 0 - 9, & - . _ ' (ampersand, dash, period, space, underscore, and apostrophe) for the name. A group name can be a maximum of 62 characters in length. For easier administration, use a name without spaces. Do not use a name that is in use as the name of an organizational unit in the hierarchical name scheme.
Note Do not create group names containing a / (slash). Using the / in group name causes confusion with hierarchical naming.
Ist das alles so?
