hi list, I can't able to create users having decimal point(s) in their name. i.e nav.neet Notice: decimal point between nav & neet. #useradd nav.neet userdd: invalid user name 'nav.neet' Since, this server will be used as Mail Server & my existing mail server (qmail on Redhat 6.2) supports DOTs in user name.Due to this problem, i export users from my existing server to new server. So, no upgradation mail !!!. OS used/tested: Redhat 9 Fedora Core 1,2 & 3 OS that supports DOTs in user name: Redhat 6.2.7.2 & 7.3 Tested by others(successfully): HP-UX,Solaris & Debian Woody Any help on this regards? Thanks in advance. Regards, Navneet -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
