Issue/Introduction

In the documentation it is stated how to assemble the XML files for syncing the users via LDAP sync tool:

Configuring LDAP Sync Client Settings (automic.com)

LDAP Sync documentation states that you can define multiple domain controllers with comma separated:

url: The IP address of the LDAP server or its fully qualified domain name and communication port on which the LDAP server listens.
Note: To specify multiple servers, separate the url entries with a comma. The first server where a connection can be established will be used.
Example: ad01.mycompany.com:389,ad02.mycompany.com:389

However when this is done, for example:

 <Connection serverName="adservers_from_domain" directoryType="AD" url="domaincontroller1.domain.com:port,domaincontroller2.domain.com:port" useSSL="true" connectionTimeout="0" readTimeout="120" searchTimeout="60" username="domain\user" password="password" retryConnect="10"/>

LDAP Sync will fail to connect to the LDAP Servers with the error below:

[main] c.a.s.l.LDAPSynchronizer ERROR Could not connect to LDAP server. Please check LDAP username and password.
com.automic.sara.ldapsync.ldap.LdapOpenConnectionException: Could not connect to LDAP server. Please check LDAP username and password.
