Running 2 Policy Servers with 2 LDAP Policy Stores on the CA Directory, the users were unable to log in to the application portal.
The error:
Can't connect to the LDAP server
shows up in the smps.log.
Both the Policy Servers are having problems connecting to both Policy Stores for an hour.
At the outage time, 1 Policy Store has been shut down twice, and a new instance of Policy Store has been discovered from the first one configuration files.
The new Policy Store had configuration problems, as it sometimes refused connection from the first Policy Store.
To work fine, both Policy Servers need to access both Policy Stores and their data should be fully accessible.
Ensure all instances of CA Directory Policy Stores are up and running, and they are accessible to fix this issue.
