Hi Fajar,

I have configured the code in the post-auth section. When the first pool is
exhausted it tries to give from the secondary, but although there are free
ips it fails. I tried changing the order of the pools, putting the secondary
pool first and it gives addresses correctly, so this pool is well
configured. 
Here is the output:

+++[basic_pool] returns notfound
+++? If (notfound)
? Evaluating (notfound) -> TRUE
+++- entering if (notfound) {...}
++++[control] returns notfound
........
[basic_pool2] No available ip addresses in pool
++++[basic_pool2] returns notfound
+++- if (notfound) returns notfound
++- if("%{control:Pool-Name}" == "redundant_pool") returns notfound

Any idea?
