Password cache Ldap

Hello,
I configured Ldap authentication in Grafana 11, but I noticed the following:
I can log into Grafana with an AD user without any problems, but when changing that user’s password in AD, I can log into Grafana with both the old password and the new password, after about 10 minutes it starts to authenticate only with the New Password.
I would like to know how to disable this password cache, because when changing the password in AD I would like it to no longer be possible to log in with the old password the way it is happening.
