Never heard of the winbind 'lwicompat_v4' backend, what is this ?

Your workgroup is 'companyworkgroup' so I would expect 'ALL' to
actually be 'COMPANYWORKGROUP'

This is the old way of doing things, I would expect to see lines like
this (if using the winbind 'rid' backend).

    idmap config * : backend = tdb
    idmap config * : range = 2000-9999
    idmap config COMPANYWORKGROUP : backend = rid
    idmap config COMPANYWORKGROUP : range = 10000-33554431
