Remarks:  If a value that you supply contains spaces, use quotation marks   around the text (for example, "CN=John Smith,CN=Users,DC=microsoft,DC=com").  If you enter multiple values, the values must be separated by spaces  (for example, a list of distinguished names).     Commas that are not used as separators in distinguished names must be  escaped with the backslash ("\") character  (for example, "CN=Company\, Inc.,CN=Users,DC=microsoft,DC=com").  Backslashes used in distinguished names must be escaped with a backslash  (for example,  "CN=Sales\\ Latin America,OU=Distribution Lists,DC=microsoft,DC=com").
