I agree that PLAIN/LOGIN should not be enabled by default as it is inherently insecure and should not be encouraged. It can easyly be enabled in a custom .mc file, if wanted, with define(`confAUTH_MECHANISMS', `')dnl define(`confTRUST_AUTH_MECH', `')dnl The snag is that is has to be enabled in the build of the SASL library. The same with KerberosIV and GSSAPI depending of what is installed. N.B This is for 8.10. I havent looked if it has changed for 8.11. If autentication is enabled with SASL, support should be added to adduser/rmuser, or we will have a supportbomb when locally defined user cant send mail remotely. > > -- > Hajimu UMEMOTO @ Internet Mutual Aid Society Yokohama, Japan > ume@mahoroba.org ume@bisd.hitachi.co.jp ume@FreeBSD.org > http://www.imasy.org/~ume/ > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-current" in the body of the message > > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
