How get access to ldap custom field value

[Nova Squad]

I'm using ScriptRunner with an ldap multi picker custom field.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.sal.api.component.ComponentLocator


def issue = ComponentAccessor.getIssueManager().getIssueByCurrentKey('Test-22')


def Groups = CustomFieldManager.getCustomFieldObject("customfield_23702")
def GroupsValue = issue.getCustomFieldValue(Groups)


return GroupsValue

The return I get from this is in the format

[CN=Group Name,OU=Groups,OU=Teams, CN=Group2 Name,OU=Groups,OU=Teams]

However when the custom field is displayed in Jira it just shows Group Name, Group Name 2

How can I retrieve just the displayed format names instead of the full base dn?

Thanks,
