Randomly users are unable to login. They receive a “invalid username/password” when they try but others are logged in just fine. The problem starts after the majority of the users are already on for the day. The following are some of our stats
Windows 2008 R2 server running Openfire 3.7.1
LDAP integrated using the following
ldap.searchFilter (&(objectClass=organizationalPerson)(|(memberOf:1.2.840.1135188.8.131.521:=CN=Pit SparkUsers,OU=…)
Also, does Openfire auth to the LDAP server everytime a user logs in or is information cached in the DB?
