NIST SP 800-63-3B sets a recommendation to have password length upper bound limited in A.2:
https://pages.nist.gov/800-63-3/sp800-63b.html#appA
Users should be encouraged to make their passwords as lengthy as they
want, within reason. Since the size of a hashed password is independent
of its length, there is no reason not to permit the use of lengthy
passwords (or pass phrases) if the user wishes. Extremely long passwords
(perhaps megabytes in length) could conceivably require excessive
processing time to hash, so it is reasonable to have some limit.
FreeIPA already applied 256 characters limit for non-random passwords
set through ipa-getkeytab tool. The limit was not, however, enforced in
other places.
MIT Kerberos limits the length of the password to 1024 characters in its
tools. However, these tools (kpasswd and 'cpw' command of kadmin) do not
differentiate between a password larger than 1024 and a password of 1024
characters. As a result, longer passwords are silently cut off.
To prevent silent cut off for user passwords, use limit of 1000
characters.
Thus, this patch enforces common limit of 1000 characters everywhere:
- LDAP-based password changes
- LDAP password change control
- LDAP ADD and MOD operations on clear-text userPassword
- Keytab setting with ipa-getkeytab
- Kerberos password setting and changing

ipa-getkeytab command was augmented in a way that allows more flexible
selection of bind mechanisms:
* -H <LDAP_URI> option was added to specify full LDAP uri. By default the
URI will be constructed from retrieved server name as is done now.
Specifying this options precludes use of -s.
* -Y <EXTERNAL|GSSAPI> specifes SASL bind mechanism if no bind DN
was given (which implies simple bind)
This allows the command to be used also locally via LDAPI, eliminating the
need to provide any credentials at all as root (e.g. in installers)
