</span>Password policy is something best enforced centrally in the authentication server and<br>
password management system. So IMHO this serves as perfect example for proprietary<br>
attributes you won't need.<br>
<br>
How is authentication done? SSH keys, Kerberos, LDAP simple bind?<br></blockquote><div><br>Kerberos <br><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

</span>Is the existing environment also an LDAP server with this particular AIX schema?<br></blockquote><div><br></div><div>no, it is a custom/legacy solution wich does not use LDAP but local accounts which are centrally managed. <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Or are you trying to follow a migration path to LDAP suggested by IBM docs?<br>
<br></blockquote><div><br></div><div>no, i've adapted some freeipa document which describes the client setup for aix (in original form it does not work and it needed some modifications) , but i have to admit that the documentation for integrating unix clients is poor and incomplete . IBM does recommend TDS, which integrates seamlessly with both AIX and Linux clients + other features which should help in integrating in heterogeneous environment, but i am not evaluating that solution currently (i may look into it only if i cannot integrate it with IPA in the way i want). <br> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Being in your position I'd first compile a list of functional and security requirements<br>
and ask then whether these requirements can be implemented with FreeIPA. I'm curious to<br>
learn whether "some other security related attributes" are still needed after all.<br>
<br></blockquote><div>all the password restriction policies (minage, maxage, number of characters in the password, history of the old passwords, number of characters, password dictionaries , etc) , loginretries - which "locks" the account after a number of unsuccessful logins , hostsallow/deny login , all the ulimit related parameters (that can probably be ignored) . It is not a matter if they increase the security or not or if they are really needed, but a matter of complying to some security standards agreed between two parties . It would be easy to keep them in the same format than to change the security standard , tooling and processes behind (bureaucracy , overhead and complexity of the enterprise environment makes me try to avoid that as much as possible , especially when there are many people and departments involved , with their own mindset and playing different politics). <br></div><div><br><br></div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
