Hi David,

The patch looks good but being not familiar with that code, my comments may be absolutely wrong

In ipadb_get_pwd_expiration, if it is not 'self' we set '*export=mod_time'.
If for some reason 'mod_time==0', it has now a specific meaning 'not expiring' . Does it match the comment '* not 'self', so reset */'

In ipadb_entry_to_mods, it deletes krbPasswordExpiration. But just before it adds in the mods krbPasswordExpiration=0 or krbPasswordExpiration=entry->pw_expiration
Could we skip those mods if entry->pw_expiration==0 or expire_time==0 ?

In ipapwd_SetPassword, ipapwd_post_modadd, same remark as above.

Something that I am not sure is what is the expected relation between passwordexpirationtime and krbPasswordExpiration

That patch looks suspiciously short given the struggles I saw in

Instead of setting to IPAPWD_END_OF_TIME, should we instead avoid
"krbPasswordExpiration" attribute at all, i.e. have password *without*
expiration? Or is krbPasswordExpiration mandatory?
So I looked at the MIT code, and it seem like they are coping just fine
with a missing (ie value = 0 internally) pw_expiration attribute.

So if we make our code cope with omitting any expiration if the
attribute is missing then yes, we can mark no expiration with simply
removing (or not setting) the krbPasswordExpiration attribute.
The attribute itself is optional and can be omitted.

I think this is a good idea, and is definitely better than inventing a a
magic value.


Just a note: I tested David's patch and it actually doesn't work when
the new password policy for ipausers group is created (priority = 0,
which should be the highest priority). The maxlife and minlife values
are empty. Even if I set the new password policy maxlife and minlife to
0 the result was that password will expire in 90 days. The patch worked
correctly when I changed value of maxlife and minlife to 0 in
'global_policy'. Then the password expiration was set to 2038-01-01.


I hope I've finally find all the places in ipa-kdb and ipa-pwd-extop plugins to tickle in order to have password that don't expire. Updated patch attached.
