Invalid unique identifier LDAP

Error:

After setting up Adeptia to use LDAP with SSL configured, I am receiving the following error on the log in screen -

Login failed - Please enter valid attribute for unique identifier in configuration xml file

Cause:

The the "uniqueIdentifier" property in the ldapConfiguation.xml file is incorrect

Solution:

Change the "uniqueIdentifer" property to a valid attribute, such as uid or samAccountName

<field name="uniqueIdentifier"
Comment="Enter the unique identifier attribute of user in LDAP server">
<mapped-to>uid</mapped-to>
</field>
