[Serusers] auth_identity module

hi, did someone check auth_identity module. I have a problem with it: in ser configuration file, for authorizer service, need 4 parameters: # -- Authorizer Service parameters ---------- #-- privatekey_path ------------------------ modparam("auth_identity","privatekey_path",".../etc/CertAuth/private/m1key.pem") #--- certificate_path ----------------------- modparam("auth_identity","certificate_path","var/www/ssl/m1cert.crt") #--- certificate_url ------------------------ modparam("auth_identity","certificate_url","http://..../m1cert.crt") #--- msg_timeout ---------------------------- modparam("auth_identity","msg_timeout",600) when i run it, there is error: WARNING: no fork mode 0(9496) init_tcp: using epoll_lt as the io watch method (auto detected) 0(9496) Maxfwd module- initializing 0(9496) AUTH_INDENTITY:mod_init: unable to open certificate 'No such file or directory' 0(9496) init_mod(): Error while initializing module auth_identity ERROR: error while initializing modules I have checked the path of this certificate (that I had created): mml@kaneway:/var/www/ssl$ ls m1cert.crt I don't know why unable to open certificate with 'No such file or directory'. Can someone tell me what is my problem here. Thanks in advance Tuan.
