Check Text (C-215229r991587_chk)
From the command prompt, run the following command to check if the default "dictionlist" attribute is set:
# lssec -f /etc/security/user -s default -a dictionlist
The above command should yield the following output:
dictionlist="/etc/security/ice/dictionary/English"
If the above command shows an empty string for default "dictionlist" attribute, this is a finding.
From the command prompt, run the following command to check if "dictionlist" attribute is set for all users:
# lsuser -a dictionlist ALL
The above command should yield the following output:
root dictionlist=/etc/security/ice/dictionary/English
daemon dictionlist=/etc/security/ice/dictionary/English
bin dictionlist=/etc/security/ice/dictionary/English
sys dictionlist=/etc/security/ice/dictionary/English
If any user's "dictionlist" attribute is empty, this is a finding.
Fix Text (F-16425r294139_fix)
From the command prompt, run the following command to set "dictionlist" attribute for the default stanza in "/etc/security/user":
# chsec -f /etc/security/user -s default -a dictionlist="/etc/security/ice/dictionary/English"
From the command prompt, run the following command to set "dictionlist" attribute for users who have an empty "dictionlist" attribute:
# chsec -f /etc/security/user -s [user_name] -a dictionlist="/etc/security/ice/dictionary/English"
