Hello, There are NAS devices (Mikrotik) in our network that generate incorrect User-Names in Access-Request packets containing spaces - example: User-Name = "MK-TRA eth 0/9:269.ether8" These packets are refused and invalid by the radius server: Invalid user (Rejected: User-Name contains whitespace): [MK-TRA eth 0/9:269.ether8] The question is - is there a way/how to do a preprocessing on the radius server to remove the whitespace characters from the User-Name? I know that the most correct solution would be to generate valid radius packets on the client side, but I already looked into the RouterOS documentation and there seem to be no fine control on how the packet is generated (User-Name is obviously constructed from configuration items, separated by said whitespaces). Any practical advice would be greatly appreciated, thank you very much in advance. -- Regards, Daniel Ryšlink
