Fix Recommendation

From the command prompt, run the following command to set "minloweralpha=1" for the default stanza in "/etc/security/user":
# chsec -f /etc/security/user -s default -a minloweralpha=1

For each user who has "minloweralpha=0" set its "minloweralpha" to "1" by running the following command from command prompt:
# chsec -f /etc/security/user -s [user_name] -a minloweralpha=1

Check Contents

From the command prompt, run the following command to check the system default "minloweralpha" attribute value:
# lssec -f /etc/security/user -s default -a minloweralpha
default minloweralpha=1

If the "default minloweralpha" value is not set, or its value is less than "1", this is a finding.

From the command prompt, run the following command to check "minloweralpha" attribute value for all accounts:
# lsuser -a minloweralpha ALL
root minloweralpha=1
user2 minloweralpha=2
user3 minloweralpha=1

If any user's "minloweralpha" value is less than "1", this is a finding.
