PROBLEMS WITH PDC AND ADMINISTRATOR

[ASISTENCIA Y SOLUCIONES INFORMATICAS 24H]

Recently I Sucessfuly configure my samba as PDC.
Now I have got a problem.
Reading the faq, I saw that the options domain group map, domain user
map and local group map are nedeen to create an administrator.

I use it to create an user like administrator of the domain, but doesn´t
works.

The comand testparm say that this parameters are unknow....

Who must I do it? Need I  a special version of samba to do It works???

My samba version is 2.5a
