Reinitialize the LDAP server. The command fails if the connection state of the LDAP server is not in an ACTIVE or READY state.
To ensure that any changes are used when a user next authenticates, it is recommended that you refresh the LDAP server after making any changes to the TRUSTED_CERTIFICATES_FILE database option or to the contents of the file specified by the TRUSTED_CERTIFICATES_FILE database option.
ALTER LDAP SERVER LDAP_server_name WITH REFRESH
