Hello

I am using several LDAP connections to Keycloak.  
One problem is that sometimes the connection to an LDAP server is unstable.  
For example, if I have LDAP servers named A to E and the connection between Keycloak server and C becomes unstable, I cannot search for users in Keycloak.  
When I checked the log, Keycloak found a user in A, but since then, it has been looking up users in all LDAPs of B~E.  
Meanwhile, Keycloak fails to communicate with C, occurring in a java.net.UnknownHostException error.  
I want to stop searching further when the user is searched in A.  
Is there a way to solve this problem?

Thank you
