Hi , I am unable to mount the share with centrify-samba . Here is the details. server : Red Hat Enterprise Linux Server release 5 (Tikanga) kernel : 2.6.18-8.el5xen The rpms installed asssocited to samba and centrify : CentrifyDC-samba-3.0.23b-3.0.4.434 CentrifyDC-3.0.8-809 CentrifyDC-openssh-4.3p2-3.0.0.172 CentrifyDC-idmap-3.0.4-434 Here is the /etc/samba/smb.conf : ______________________________________________________________________ [global] security = ads realm = xxxxxx.xxxxxx.ORG workgroup = EHEALTH netbios name = lnlab013 server string = Samba-CDC auth methods = guest, sam, winbind machine password timeout = 0 idmap backend = /usr/share/centrifydc/lib/idmap_centrifydc.so idmap enable cache = No idmap uid = 500-100000000 idmap gid = 500-100000000 template shell = /bin/bash client use spnego = no server signing = auto client signing = auto winbind use default domain = Yes winbind enum users = No winbind enum groups = No winbind nested groups = Yes log file = /var/log/samba/smbd.log [data] path = /data browseable = yes writeable = yes guest ok = yes create mask = 0777 force directory mode = 777 force group = users _______________________________________________________________________ Cenrify is working fine , also the centrify-ssh, The user/pass are authenticated from Active Directory. There is no issues. But when I am trying to mount the unix share from my latop, then it is not mounting. The errors are in the log file as follows: 2009/01/13 15:13:47, 0] libads/kerberos.c:ads_kinit_password(208) kerberos_kinit_password <server>$@<FQDN> failed: Preauthentication failed 2009/01/13 15:13:47, 0] printing/nt_printing.c:nt_printing_init(649) nt_printing_init: error checking published printers: WERR_ACCESS_DENIED [2009/01/13 15:13:47, 0] auth/auth_util.c:create_builtin_administrators(784) create_builtin_administrators: Failed to create Administrators [2009/01/13 15:13:47, 0] auth/auth_util.c:create_builtin_users(750) create_builtin_users: Failed to create Users [2009/01/13 15:20:32, 1] smbd/sesssetup.c:reply_spnego_kerberos(202) Failed to verify incoming ticket! My confusion is , the same login i am using to login to the unix hosts, but with same user/pass samba is not accepting. I never worked on samba and no concept either I have with windows... Help is really appreciated. Thanks again
