Account setting

How to setup "No accounts are allowed to have a null password."

[Vitaly Karasik_1]

check /usr/share/doc/pam-0.XX/txts/pam.txt
(in RHEL 4 there is pam-0.77).
I guess, you should add "nullok" option in appropriate pam configuration.

I check my ES4.0,but I can't find how to config .

[Tom Robinson_1 · Accepted solution]

nullok can be configured in the /etc/pam.d directories. Usually on RHEL systems the file to change is system-auth but beware that this file is generated by the system-config-authentication utility and may be overwritten if someone subsequently runs it.

By default on RHEL systems, null password accounts are locked so I'm not sure why you want to change the pam settings.

Kevin,

Take a look at this doc, it should help you out, just do a search for null passwords,
