Rocket.Chat 1.0.3 LDAP Sync parameter problem

Hi,
I have using rocket.chat from 6 months version 0.73 with LDAP authentication. For username sync i have been using "displayName" parameter. But after upgrade to 1.0.3 this settings does not work. If i change to "sAMAccountName" it's working, but this not work for me, because with this parameter Rocket.chat create account for every computer and group. Can you help me

This is the error from log file

Exception in callback of async function: TypeError: Cannot read property 'replace' of undefined at module.exports (/opt/Rocket.Chat/programs/server/npm/node_modules/limax/lib/limax.js:18:15) at slug (app/ldap/server/sync.js:22:9) at ldapUsers.forEach.ldapUser (app/ldap/server/sync.js:303:16) at Array.forEach () at ldap.searchUsersSync.Meteor.bindEnvironment (app/ldap/server/sync.js:290:13) at runWithEnvironment (packages/meteor.js:1356:24)
