Hi Alan,

thanks for your advice Alan.
it works if we use "update request" instead of "update control".

  Yes.  You can just use a regular expression.

if (TLS-Client-Cert-Subject =~ /UID=(.*)/) {
update control {
Stripped-User-Name = "%{1}"
}
}

  If you don't want to use Stripped-User-Name, just edit
raddb/dictionary, and define a local 'string' attribute there

  Edit the filters to use Stripped-User-Name, or whatever else you
defined above.
