In order to construct LDAP authentication,the Authentication key value needs to be updated with “LDAP” in the backendsettings file. 

<Setting Value="LDAP" Key="AuthenticationModule"/> 

In addition to this, the following values needs to be filled with the correct values. 

<Setting Value="SERVER" Key="LDAPDomainName"/> 

<Setting Value="389" Key="LDAPPortNumber"/> 

<Setting Value="dc=server,dc=com" Key="LDAPBasedn"/> 

<Setting Value="" Key="LDAPUsername"/> 

<Setting Value="" Key="LDAPPassword"/> 

Also, RoleMappingFile.xml needs to be created with the following content under C:\ProgramData\IDScan\IDScanEnterprise\ 

This content allows specified users who are member of the specified user groups, to be authenticated. 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 

<RoleMapping xmlns:xsi="http://ww.w3.org/2001/XMLSchema-instance"> 

  <RoleMappingItem> 

    <RoleName>IDScan Scan Users</RoleName> 

    <MappedRoleName>Scan User</MappedRoleName> 

  </RoleMappingItem> 

  <RoleMappingItem> 

    <RoleName>IDScan Scan Reviewer</RoleName> 

    <MappedRoleName>Scan Reviewer</MappedRoleName> 

  </RoleMappingItem> 

  <RoleMappingItem> 

    <RoleName>IDScan Setup Administration</RoleName> 

    <MappedRoleName>Setup Administrator</MappedRoleName>  

  </RoleMappingItem> 

  <RoleMappingItem> 

<RoleName>IDScan System Administration</RoleName> 

    <MappedRoleName>System Administrator</MappedRoleName> 

  </RoleMappingItem> 

  <RoleMappingItem> 

    <RoleName>IDScan Report Users</RoleName> 

    <MappedRoleName>Report User</MappedRoleName> 

  </RoleMappingItem> 

</RoleMapping> 

RoleMapping file’s path should be indicated in web.config file like below: 

add key="RoleMappingFilePath" value="C:\ProgramData\IDScan\IDScanEnterprise\RoleMappingFile.xml" /> 

IIS should be restarted after LDAP configuration.
