Usermapper

So I’m doing to migrations from Celerra FS’s to VNX. For pure CIFS domain joined servers, the NTFS permissions
are on the files and the share permissions are on the VDM, so what does the
usermapper file do? I always copy the usermapper file during these
migrations.  But I’m wondering what it actually does?  What would
happen if I didn’t copy the usermapper and then failed over?

Just curious if anyone knows?  Thanks!
