I don't know about the osers, but about password length: Yast - security and users - custom - on the second screen you have the password length screen Regards, Radu ----- Original Message ----- From: "lars" <lars@brainlift.de> To: <suse-security@suse.com> Sent: Friday, March 28, 2003 3:33 PM Subject: [suse-security] How to handle usernames? Hi there, I´ve got a strange behaviour which I want to get rid off ... though it may not be the right group here: on a suse linux 8.1 box, doing useradd -s /bin/false -d /... and-so-on ... b.richards to add a mailuseraccount, I always got the reply: invalid username The same with useradd -s /bin/false -d /... and-so-on b\.richards OK, then I´m typing ³useradd brichards², editing the /etc/passwd as well as /etc/shadow (e.g. setting in the dot manually), then typing in the password, but then ... the client sometimes gets an errormessage from postfix - sometimes it works fine. I found out that in case of unvalid usernames always almost a ³!² is shown in the second field in /etc/shadow-uservalue-lines (where there have to be the shadowed password). everything works fine with usernames without a dot. I tried hard to find some informations about this, but the only restriction valid for all shels seemed to be avoiding ³:² and ³/² in usernames. Anyone a suggestion? would be helpfull... thanx a lot! greetings Btw: how can I change the length of a password to a value higher than 8? Possible at all on a bash or tcsh? -- Check the headers for your unsubscription address For additional commands, e-mail: suse-security-help@suse.com Security-related bug reports go to security@suse.de, not here
