First I should say thanks for your continous help. I did what you said. You are right it has problem with blanks. Here is the result: There are same results when /etc/raddb/server is configured normally and also when I add some blank lines after IP address. Jun 7 10:22:34 test saslauthd[16217]: rel_accept_lock : released accept lock Jun 7 10:22:34 test saslauthd[16218]: get_accept_lock : acquired accept lock Jun 7 10:22:34 test saslauthd[16217]: pam_radius_auth: Got user name fatemeh Jun 7 10:22:34 test saslauthd[16217]: pam_radius_auth: Unable to open socket5: Success Jun 7 10:22:34 test saslauthd[16217]: pam_radius_auth: Not handling blank line: # server[:port] shared_secret timeout (s) Now how I should solve this problem? By the way, why it does not go furthur to socket10 or socket23 tags ? Thanks Fatemeh Taj __________________________________ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!
