[Samba] authentication problem with samba4 as a dcerpc server

[eric gou]

I made a mistake in the previous letter. I use the command “net ads join”, looks that’s not for the samba4,

now I use the “samba-tool” to join a DC domain as a member, and it succeed, I can see some info stored in 

secrets.ldb.

./samba-tool domain join SMB3.COM MEMBER -Uadministrator --realm=SMB3.COM


unfortunately, when I start the “samba”, it still fails to find the domain info, so as to the latter authenticating for msrpc:

task_server_terminate: [dreplsrv: no DSDB replication required in domain member configuration]
single_terminate: reason[dreplsrv: no DSDB replication required in domain member configuration]
ldb_wrap open of secrets.ldb
task_server_terminate: [Cannot start Winbind (domain member): Failed to find record for SMB3 in /usr/local/samba/private/secrets.ldb: No such object: (null): Have you joined the SMB3 domain?]

any one can help?

thanks
