Good day I want to create POP3 accessible only for some user from different computers. I tried use PAM. I tried add into /etc/pam.d/pop these lines: auth required /lib/security/pam_rhosts_auth.so account required /lib/security/pam_rhosts_auth.so In this moment POP3 stop work . I found "PAM unable to resolve symbol: pam_sm_acct_mgmt" in the log. I can not found what is wrong. I use RedHat 7.0 with pam-0.72-37 and imap-2000-3. Thank you. Petr SPATKA
