LDAP Auth. works, but stops after a day

[Tythagoras]

My server is running Ubuntu 20.04, along with a Nagios install. I managed to get Cacti working with LDAP to authenticate against our Windows Active Directory for authentication, and it works great. Now, if I log out and stay logged out for a day or so (I haven't tested the exact interval required), I can no longer log in via an LDAP account, even with different accounts that I have through AD. It gives an authentication error message, as if I had mistyped my password. Logging in with the local admin account and logging out restores the LDAP functionality. Anyone heard of this or something like it before? I set the logging level to HIGH, but I haven't figured out how to filter out the routine stuff, so if there's something there, it's lost in all the POLLER, PING, AUTOM8 and similar entries. I'm not getting locked out in AD, so I'm not sure if it's hitting the domain controller or not when it's not working.

I forgot to mention I'm using version 1.2.10

So after a few more days and tests, it will still stop letting me log into my LDAP accounts sometime after 24 hours, but I just tested it and I put in my domain credentials twice, and just for laughs, I changed the type on the login screen from LDAP to local, then back to LDAP. Then it let me log in. So I guess that's not a blocking issue anymore, but it's a little weird.
