Hello Rajendram,
Do you want to configure Real name and the company name on the user profile on ACS Windows? If so, there is a field in the userprofile Under Supplimentatry User Info section to specify the Real name. In the decription, you may want to specify the company name. Please, keep in mind that this is good for easier administration purpose, this information will not be passed down to any NAS device.
Please, let me know if this answers your question. Thanks,
Mynul
