Freeradius acct_unique模块软件包在OpenWrt CC-15.05.1上不可用

Question

I'm running Openwrt CHAOS CALMER (15.05.1, r48532) on my linksys WRT1900AC V1 (mamba - mvebu platform).

I have installed freeradius server version 2.2.8, i'm facing troubles with the acct unique session id which is all the time empty:

rlm_sql_mysql: MYSQL check_error: 1062 received
[sql] Couldn't insert SQL accounting STOP record - Duplicate entry '' for 
key 'acctuniqueid'
rlm_sql_mysql: MYSQL check_error: 1062 received
rlm_sql_mysql: Cannot store result
rlm_sql_mysql: MySQL error 'Duplicate entry '' for key 'acctuniqueid''
rlm_sql (sql): Released sql socket id: 9
++[sql] = fail
+} # group accounting = fail
Finished request 21.
Cleaning up request 21 ID 5 with timestamp +1271
Going to the next request
Ready to process requests.

Reading the freeradius mailing list it seems that the only solution is to use the "acct_unique" module which is not available for download using the opkg install tool from OpenWrt console. I beg any one who have this package (ipk already compiled for the mvebu platform) or he have the OpenWrt build system and he can cross compile this module to help me sort my issue by helping me to get this module for my platform.

Any other alternative solutions to sort out this problem using shell scripting call from the freeradius daemon are welcome.

Here is the list of packages available for freeradius :

Edit raddb/policy.conf

Add

acct_unique {
    update request {
            Acct-Unique-Session-Id := "%{md5:%{User-Name},%{Acct-Session-ID},%{NAS-IP-Address},%{NAS-Identifier},%{NAS-Port-ID},%{NAS-Port}}"
    }
}

You can then add a call to acct_unique in raddb/sites-available/default at the top of the preacct {} section, to generate the Acct-Unique-Session-ID attribute.
