LDAP configuration in Mimecast can help to improve productivity by enabling you to securely automate the management of Mimecast users and groups using your company directory. As you prepare to move your email flow to Mimecast, you can use the Mimecast Directory Sync tool for LDAP integration with email clients that include Microsoft Office 365, Microsoft Outlook and Microsoft Exchange to eliminate the administrative burden of managing Mimecast users and groups manually. LDAP configuration will also enable you to take full advantage of Mimecast features and reduce the time required for configuring and maintaining services.

Troubleshooting LDAP configuration.
When LDAP configuration does not work properly the first time, one of the following common errors may be the cause.
Directory connection connectivity failure. If LDAP configuration does not enable Mimecast to connect to your organization's environment, the connection to the IP address that has been specified for the directory connector will fail in Mimecast and will be unable to synchronize with the directory server.
Active directory credential failure. When a user account in the customer infrastructure does not match account details configured in the Mimecast Administration Console, the connection will fail and Mimecast will be unable to log on to synchronize the directory.
Special character requirements. If attributes in your directory structure use special characters, you'll need to escape them by prefixing them with a backslash in the attribute string.
