[Samba] winbind pam trouble

[lists]

Some other observations in log.winbindd-idmap:

> [2016/04/12 08:37:54.028456,  1] ../source3/winbindd/idmap_ad.c:523(idmap_ad_sids_to_unixids)
>   Could not get unix ID for SID S-1-5-21-90839350-987482234-868425949-133237

This happens for 30 different SID's: some with a long last RID:

> Could not get unix ID for SID S-1-5-21-90839350-987482234-868425949-133237
> Could not get unix ID for SID S-1-5-21-90839350-987482234-868425949-132270
> Could not get unix ID for SID S-1-5-21-90839350-987482234-868425949-132722

and with shorter RID's like
> Could not get unix ID for SID S-1-5-21-90839350-987482234-868425949-501
> Could not get unix ID for SID S-1-5-21-90839350-987482234-868425949-502
> Could not get unix ID for SID S-1-5-21-90839350-987482234-868425949-517

However, and looking at an ldif dump of our CN=Users, I can't find these 
numbers...?

Anyone..?
