Dialup-Admin Alternatives?

[JaxxMaxx the Elder Druid]

Greetings folks!

I'm wondering if there is something else that other folks are using to allow GUI administrative access to  FreeRadius w/MySQL-stored user databases.
I'm noticing that the Dialup-Admin  web interface is leaving a LOT to be desired, and doesn't appear to be keeping up with the rest of the FreeRadius updates.  I had to modify some of the .sql schemas, and I'm still getting PHP errors on some of the interface pages. 
** Warning: mktime() expects parameter 1 to be long, string given in /usr/share/freeradius-dialupadmin/lib/functions.php3 on line 95 **

Does anyone still use this interface with the current 2.0.3 ?
What other methods do you use to allow non-SQL savvy administrative folks to add and remove valid usernames for authentication?

Basically, this web interface is the last thing standing in my way of fully implementing the newer version of FreeRadius (needed to move to different hardware, supporting a captive portal device on a Wifi network)
