ldap loader display name doesnt change

Hi,

i'm using an LDAP_GROUP_LIST loader with this parameter :

grouperLoaderLdapGroupDisplayNameExpressionName :
Services:${groupAttributes['cn']}:Tous

Recently, for this case, the value of LDAP attribute CN was changed.
I used the loaderRunOneJob command but the displayName was not updated,
it's still the old value...

Is that normal ? Can you help me ?

Thanks,
Yoann
