EAP-SIM authorize

Hi, I am working on a modified rlm_sim_files which uses an SQLite database instead of the text file. It works, but within one run of the EAP-SIM protocol, the module runs 3 times (once for every incoming EAP message) and searches the database/file 3 times. This consumes valuable time and if I delete the triplet in the first run (I want to use a triplet only once), it won't even succeed to authenticate. Is there a way to solve this, I mean to tell the sim_files authorize module that it already provided the necessary auth info, and should just say OK without any search? Is the eap_sim module capable of rememering the RAND-SRES-Kc values? Thanks for the answer in advance, Andras
