Trouble using % percent sign in usernames with MySQL auth

[Jonas Frey]

Hello,

i am running into problems while using usernames which include a percent
% sign. The rlm_sql_mysql module apparently translates these into the
ascii of "=25". So a username which was isp/somebody%somewhere gets
translated into isp/somebody=25somewhere.

Additionally these users are listed incorrect via dialup admin. If you
click on their names (even if they include the =25) you cant administer
them since dialupadmin apparently strips out the equalsign (as well as
the percent sign).

Is anyone observing similar behaviour and/or knows of a fix?

Regards,
Jonas
