Hi,

The most probable reason is having different versions of samba binaries 
installed. Using net ads ... suggests the use of samba3 client tools 
installed from packages, the path /usr/local/samba/private/secrets.tdb 
suggest a Samba built from source via ./configure && make && make 
install (which corresponds to a Samba4 install)
