* cifsacl is the mount option.
* When passed, it makes cifs.ko call the userspace program cifs.idmap
everytime it has to map a SID.
* cifs.idmap has a winbind or sssd backend (dynamicly loaded librairies
* The winbind backend is idmapwb.so and is linked against libwbclient
and uses the same calls as wbinfo to do the mapping. Thus it returns
the same IDs.
I picked this SID as an example of a SID that doesn't map, I don't know
what sort of SID Ken is seeing.
If Ken is seeing a mapping error in the logs and also with wbinfo for
regular AD users it is likely something is wrong with his winbind setup.
