Hi

Email address is mandatory field, otherwise it will throws error. Basically If we are using LDAP resource handler  the following three fields are mandatory.

1. purpose = identifier

2. purpose = name

3. purpose = email.

Please try this and let us know results. Find below sample LDAP resource handler for your reference.

<?xml version="1.0" encoding="utf-8"?>

<XmlResourceHandler>

  <Properties>

    <Property name="samaccountname" type="string" purpose="identifier" displayname="Login ID" />

    <Property name="name" type="string" purpose="name" displayname="Name" />

    <Property name="mail" type="string" purpose="email" displayname="Email" />

    <!--<Property name="title" type="string" purpose="designation" displayname="Designation" /-->

    <Property name="department" type="string" purpose="department" displayname="Department" />

    <Property name="manager" type="string" displayname="Manager" purpose="manager" suppressdn="true" />

    <Property name="memberof" type="string" purpose="group" displayname="Group" suppressdn="true" />

  </Properties>

  <Preferences>

    <SearchScope>SubTree</SearchScope>

    <ReferralChasing>External</ReferralChasing>

    <TimeOut>50</TimeOut>

    <SizeLimit>60</SizeLimit>

    <AuthenticationUser></AuthenticationUser>

    <AuthenticationPassword></AuthenticationPassword>

  </Preferences>

  <LDAPServer>LDAP://</LDAPServer>

  <LDAPSearchBase>DC=skelta,DC=dom</LDAPSearchBase>

  <LDAPBaseFilter>(objectCategory=Person)</LDAPBaseFilter>

</XmlResourceHandler>

Anil.
