> Ldap sync fails when there are special characters in distinguished names. 
> For example if there was a user with the distinguished name of {{OU=test/test,OU=users,DC=EXAMPLE,DC=COM}} and that user was a member of a synced group, then the lookup of the user using the membership attribute in the group would fail due to the special character.  
> The error would look something like
> {noformat}
> REASON: Caught exception running LDAP sync. Uncategorized exception occured during LDAP processing; nested exception is javax.naming.NamingException: [LDAP: error code 1 - 000020D6: SvcErr: DSID-031007DB, problem 5012 (DIR_ERROR), data 0
> ]; remaining name 'OU=test/test,OU=users,DC=EXAMPLE,DC=COM'
> {noformat}
> *Solution*
> Update the library versionf for Spring LDAP 
> * {{org.springframework.security/spring-security-ldap}} to {{4.0.4.RELEASE}}
> * {{org.springframework.ldap/spring-ldap-core}} to {{2.0.4.RELEASE}}
> Then use {{LdapUtils.newLdapName}} to convert a String representing a DN into a {{javax.naming.ldap.LdapName}} and use that object in the search facility executed in {{org.apache.ambari.server.security.ldap.AmbariLdapDataPopulator#getFilteredLdapUsers(java.lang.String, org.springframework.ldap.filter.Filter)}}.
