Hi,
To fix your problem you have to register the missing class, here is a PR
to get as example to register some missing class
https://github.com/apereo/cas/pull/3857/files. So you can contribute ?
After my point of view is that's a problem that KRYO need to register
all class to serialize them, but it doesn't seem to have an other way.
After there is a good beneit to use KRYO as his serialization is more
efficient than the default one.
Thanks,
Julien

Doug, thank you very much for your feedback and the workaround. That
does, indeed, fix the immediate issue at hand. Hopefully the Kryo
serialization issue will be resolved soon.
Thanks again!

I don’t know if this is an ideal workaround but I found in my case
if I changed the transcoder setting from KYRO to SERIAL that
everything starting working great.
cas.ticket.registry.memcached.transcoder: SERIAL
In the documentation it recommends using KYRO stating “This
component is recommended over the default Java serialization
mechanism since it produces much more compact data, which benefits
both storage requirements and throughput.” There are two other
options as well: WHALIN and WHALINV1.
I am not sure if it really matters which one but since the use of
KYRO seems buggy maybe the recommendation for using it is no
longer the best.

*Subject:* RE: [cas-user] Issue with LPPE and memcached ticket
registry
Gary,
I don’t have an answer but I saw this same error yesterday when I
was testing proxy authentication on my CAS 6.0.3 test setup. In
my case I haven’t configured LPPE. I did try disabling it just
now but that seemed to have no effect as the error still occurs.
In my case I am using spymemcache and not AWS Elasticache. For
now I have switched back to the default InMemory ticket registry
and proxy authentication works fine with that.
If I figured out anything I will let you know and if you discover
a solution please do report back.
Thanks!

*Subject:* [cas-user] Issue with LPPE and memcached ticket registry
Hi all,
I've been building/testing CAS v6.1.0 (HEAD), and was getting
along fairly well until I ran into an error with LPPE and the
memcached ticket registry I'm using.
I am using 389 Directory server for LDAP authentication and have
password policy configured as follows:
# LDAP Password Policy Enforcement (LPPE) parameters
cas.authn.ldap[0].passwordPolicy.type=GENERIC
cas.authn.ldap[0].passwordPolicy.enabled=true
cas.authn.ldap[0].passwordPolicy.policyAttributes.accountLocked=javax.security.auth.login.AccountLockedException
cas.authn.ldap[0].passwordPolicy.loginFailures=6
cas.authn.ldap[0].passwordPolicy.warningAttributeValue=
cas.authn.ldap[0].passwordPolicy.warningAttributeName=
cas.authn.ldap[0].passwordPolicy.displayWarningOnMatch=true
cas.authn.ldap[0].passwordPolicy.warnAll=true
cas.authn.ldap[0].passwordPolicy.warningDays=30
cas.authn.ldap[0].passwordPolicy.accountStateHandlingEnabled=true
cas.authn.ldap[0].passwordPolicy.strategy=DEFAULT
I am using memcached (with AWS Elasticache support) and am using
all of the defaults (just setting
cas.ticket.registry.memcached.servers to the configuration
endpoint node).
When I disable LPPE, everything works as expected--I can login,
get a TGC, ST validation works, etc). When I enable LPPE and set
my password expiration date to a threshold within 30 days, I get
the expected "your password is about to expire" page, with the
green "Continue" button. When I click that, I'm redirected to the
CAS login page and the following errors appear in the log:
2019-04-29 01:10:22,684 ERROR
[org.apereo.cas.ticket.registry.MemcachedTicketRegistry] - <Failed

Note: To register this class use:
kryo.register(org.apereo.cas.authentication.support.password.PasswordExpiringWarningMessageDescriptor.class);
<...followed by big stack trace...>
Is there something I'm overlooking, or failed to add, in my
config? Any pointers appreciated!
Thanks,
--Gary
