is it possible to send the mac address in lower case instead of upper case. Authenticating against Cisco ACS with a mixture of Cisco AP 1200 and mikrotik access points. Cisco sends password in lower case, need mikrotik to match
I know that this is an old POST, but a customer of mine have exactly this problem. Anyone have a solution?
Please reply,
Best Regards,

No reply mk team?
a few hours is not enough for answer =) also, you’d better write to support at mikrotik dot com
@Chupaka: i agree with you about that is better to send email to support at mikrotik dot com. But i also thing that using forum is better for community help.
So now i’ll send email to please answer at this post 
unfortunately, community still cannot modify ROS directly =)
Hi,
I am using hotspot on MikroTik V3.30 and my external radius server (Emerald Management suite V.5 with RadiusNT) cannot create a username with “:” as a character.
I am trying to do MAC Authentication on a private office network where bandwidth needs to be measured websites blocked and authentication has to be transparent.
I have set up the MAC Authentication on Usermanager a lot with no problems but the problem is the format that mikrotik uses for MAC addresses XX:XX:XX:XX:XX:XX. Even if I set the => Hotspot > Server Profile > Hsprof1 > Radius > MAC Format to XX-XX-XX-XX-XX-XX this only shows up as the caller ID in my Radius online list but it doesn’t look like that in the HotSpot hosts list. I believe this MAC Format feature is only for accounting not for Authentication. Is there a way that the MAC format used for Authentication in can be changed to “-” or “_” instead of “:”
In userman the MAC User must be set to xx:xx:… to be able to Auth all other formats are ignored as MAC’s and thought of as strings for usernames. Even if I can use XXXXXXXXXXXX as MAC this would help.
Please Help!
Thanks for the link to the original forum(*thread), so I am basically stuck until ROS can be modified by the community?
Because this is a ROS issue completely i think this should be a feature request.
We should be able to define the format of MAC’s as there is no standard accross platforms.
Someone from the Mikrotik Team Please answer
I think there is already a standard mac address format: XX:XX:XX:XX:XX:XX
I think there is also a format for ip addresses: xxx.xxx.xxx.xxx
Maybe you should contact the software company and inform them the software does not conform to recommended internet standards. That would be a good way for you to help with the standardization! 
ADD: After a quick check of the RFCs, the XX-XX-XX-XX-XX-XX mac format should also be recognized. That would be a MikroTik concern if it does not use the hyphens (-) in the user name.
Exaclty what I was thinking, hyphens would solve my problems.
If only MikroTik would conform but when this would happen is another thing altogether.
I don’t know if this is dumb but would it be possible to use some type of script for this?
Or have userman be a server to the hostpot but also a client to another radius?

Maybe you should email support (at) mikrotik.com with your problem. Maybe they don’t know it does that.
I will give that a try, thanks
