Hi Alan,

I did upgrade my free radius to 2.2.4 but still the issue persist.
I've attached the log of the same.

On looking at code flow could make out while creating the new attribute (stripped-user-name), " '\\' 't' " is replaced as '\t'.
As a fix I've made below changes.

File : src/modules/rlm_attr_rewrite/rlm_attr_rewrite.c
Function: do_attr_rewrite()
RCA : While paring attribute with value ,value is formatted and then paired. During formation " \\t " is replaced by " \t "

Fix: Before paring attribute with value, convert the value to printable formate and then send it for paring.

                        DEBUG2("%s: Could not add new attribute %s with value '%s'", data->name,
                                data->attribute,replace_STR);

Pleaseguide me in understanding if this fix will create problem in any other scenarios.

Thanks,

Adarsha

  Upgrade.  IIRC this issue was fixed.

  The latest release is 2.2.4.  You're running a version which is many
years out of date.
