Unlang is not really intended to do that. > In fact, the reason why I need this function is that sometimes we treat > some attributes as temporary variable for generating another attribute > value pair. Use Tmp-String-0, or Tmp-Octets-0 instead. That way the problem goes away. See "dictionary.freeradius.internal" for more examples. > Then erase it before sending request or reply out.

Alan DeKok. ------------- Hi Alan, Thanks for reply. Yes, I totally can understand the solution you recommend, and I've been using this skill for quite a long time. But the situation I encountered is : 1. I need to save some information returned in Access-Accept from external AAA in the attribute *Class* at the section *post-auth*. So it will return back to gateway. 2. Then gateway will send Accounting-Start to my server. In this time, I need to pop out the information I saved in the attribute *Class* in the section *accounting* so that I can generate the avp what I need. Hence, it cannot work by using Tmp-XXX internal attribute because those two events occur in two different sessions to FreeRADIUS. I thought Tmp-* attributes will not exist across two sessions at the same time. So that way I must choose some kind of attribute that gateway must return back for saving temporary attribute value. Concerning about total available length of Class in our wifi gateway, I don't want to do such a waste on attribute Class. Again, just like I said before, because Class is a multi-value attribute I can't find a way to remove a specific value from entire Class array. But anyway, if this is too much for unlang I can use perl to fulfill this definitely. Just curious about if unlang can totally achieve this. :P Cheers, Okis.
