Hello, I'm having some trouble with samba 3.0.14a and wbinfo: all the test with wbinfo -t, wbinfo -m, wbinfo -u and -g are successful but when I try to test a username it failed: bash-2.05# wbinfo -a domain\\bj%xxxx plaintext password authentication failed error code was NT_STATUS_TRUSTED_DOMAIN_FAILURE (0xc000018c) error messsage was: Trusted domain failure Could not authenticate user domain\\bj%xxxx with plaintext password challenge/response password authentication failed error code was NT_STATUS_TRUSTED_DOMAIN_FAILURE (0xc000018c) error messsage was: Trusted domain failure Could not authenticate user domain\\bj with challenge/response And when I'm using squid (that mean with ntlm_auth) it's working fine. Here is the config of smb.conf [global] workgroup = D-CI3 server string = penelope proxy %v security = DOMAIN password server = 10.17.12.56 10.17.12.57 client NTLMv2 auth = Yes client lanman auth = No client plaintext auth = No name resolve order = wins host wins server = 10.17.12.9, 10.17.17.8 idmap uid = 10000-20000 idmap gid = 10000-20000 Arno Streuli
