hi: I'm so glad to write to you. I have some question on using ser. the ua that I use is sjphone. Everyone can use the ser but unregistered. Ser don't confirm the user'username and password. I have configured ser.cfg like this loadmodule "/usr/local/lib/ser/modules/dbtext.so" loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" modparam("usrloc", "db_mode", 2) modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "password_column", "password") I don't know why it no work well! Would you like help me. Thank you very much! 姓名：张兆心 email: zhang_zhaoxin(a)pact518.hit.edu.cn
