Defines the minimum number of special characters in a password. Rationale: In setting the minspecialchar attribute, the password must contain a special character when it is changed by the user.
Solution
In /etc/security/user, set the default user stanza minspecialchar attribute to 1: chsec -f /etc/security/user -s default -a minspecialchar=1 This means that there must be at least 1 special character within a password. Default Value: default minspecialchar=0
