IPA password reset issue

Hi,

I am getting the following error when running the knit admin command. Any suggestions ?

root@server01 ~]# kinit admin
Password for admin@domain.com:
Password expired.  You must change it now.
Enter new password:
Enter it again:
Password change rejected: Current password's minimum life has not expired

Password not changed..  Please try again.

You need "kpasswd" command to change a kerberos password.

the password policy may have been changed with password expiration beyond 2038. to restore the pw policy without a working admin user, you have to consider
a) Do modifications as Directory Manager or other user in "admins" group.
b) Manually fix admin entry attribute krbPasswordExpiration to some future date
c) kinit as admin, fix global policy with some value (pwpolicy-mod)
(Likely to use ldapmodify and bind as DM since, you cannot change krbPasswordExpiration with IPA user (IIRC))

Otherwise, better to have get the user whom is also admin user, consider doing "ipa passwd" on the original (lockout) admin, assign a temporary password and have it change on first login again.

Option (C) may not be possible but both (a) & (b) look viable. Can you please elborate options (b) ?

But also note that need to take care of "The maximum lifetime setting given in the password policy (--maxlife) ", see also
To ensure that new user passwords are valid and can be changed properly, do not set password Maximum Lifetime in Identity Management Password Policy to values that would cause the Kerberos Password Expiration Time timestamp to exceed 32 bits; that is, passwords that would expire after 2038-01-19. At the moment, recommended values for the Maximum Lifetime field are numbers lower than 9000 days.

But I am thinking if you have other admin, they can reset this "admin" and force change password on first login. It has worked for other ...
