Hello, How do I rewrite the value of the User-Name attribute based on Called-Station-Id? I need to do a series of these logical decisions and replace the username with username@<some-isp.com> based on what the value of Called-Station-Id is. rlm_attr_rewrite seems the obvious choice, but I can't figure out how to use various instances of that module only when Called-Station-Id has a certain value. It seems like a strange thing to need to do, but I've thought about our problem and this is really the only scalable way. I can give a lot of background as to why, but I figured I would ask the question first. So, does anyone have any ideas? Also, thank you for all the hard work on Freeradius. Its a great piece of software. Thanks Chris Carver
