Hi We have a Samba server that authenticates with an openldap server. Or it used to. We had a power cut last week and after a bit of struggling everything came back, but not Samba. Previously our smb.conf file included the line
passdb backend = ldapsam:ldap://server.domain.net/ With this line in place the connection to the LDAP server fails, and peoples shares drop off every few minutes. I changed this to point to our 2nd, backup ldap server and now shares and logon work again. I need to get communication started again between our Samba and primary LDAP server. Symptoms include the following: (with the new config, ie pointing at the backup ldap server) On the samba server: servername:/etc/samba# smbclient '\\servername\data' WARNING: The "printer admin" option is deprecated Enter root's password: session setup failed: NT_STATUS_LOGON_FAILURE but servername:/etc/samba# smbclient -L localhost -U% WARNING: The "printer admin" option is deprecated Domain=[DOMAIN] OS=[Unix] Server=[Samba 3.2.5] Sharename Type Comment --------- ---- ------- netlogon Disk Network Logon Service print$ Disk Printer Drivers etc also: servername:/etc/samba# pdbedit -u username -c "[X]" doing parameter syslog = 1 doing parameter log file = /var/log/samba/log.%m doing parameter max log size = 1000 doing parameter smb ports = 139 doing parameter name resolve order = wins bcast hosts doing parameter printcap name = cups doing parameter add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u doing parameter add machine script = /usr/sbin/smbldap-useradd -w %m doing parameter logon script = logon.cmd doing parameter logon path = \\server.domain.net\%U\profile doing parameter logon home = \\server.domain.net\%U doing parameter domain logons = Yes doing parameter os level = 33 doing parameter preferred master = Yes doing parameter domain master = Yes doing parameter dns proxy = No doing parameter wins support = Yes doing parameter ldap admin dn = "uid=username,cn=admins,cn=thenameofthecn" doing parameter ldap group suffix = ou=groups doing parameter ldap machine suffix = ou=machines doing parameter ldap passwd sync = Yes doing parameter ldap suffix = dc=ixico,dc=com doing parameter ldap user suffix = ou=people doing parameter panic action = /usr/share/samba/panic-action %d pm_process() returned Yes smbldap_search_domain_info: Searching for:[(&(objectClass=sambaDomain)(sambaDomainName=DOMAIN))] smbldap_open_connection: connection opened ldap_connect_system: successful connection to the LDAP server The LDAP server is successfully connected smbldap_search_domain_info: Searching for:[(&(objectClass=sambaDomain)(sambaDomainName=DOMAIN))] smbldap_open_connection: connection opened ldap_connect_system: successful connection to the LDAP server The LDAP server is successfully connected init_sam_from_ldap: Entry found for user: username ldapsam_update_sam_account: user username to be modified has dn: uid=username,ou=people,dc=domain,dc=com init_ldap_from_sam: Setting entry for user: username Unable to modify entry! If I change the setting back to point at our original LDAP server I get the following errors, for example: servername:/etc/samba# pdbedit -u username -c "[X]" doing parameter syslog = 1 doing parameter log file = /var/log/samba/log.%m doing parameter max log size = 1000 doing parameter smb ports = 139 doing parameter name resolve order = wins bcast hosts doing parameter printcap name = cups doing parameter add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u doing parameter add machine script = /usr/sbin/smbldap-useradd -w %m doing parameter logon script = logon.cmd doing parameter logon path = \\server.domain.net\%U\profile doing parameter logon home = \\server.domain.net\%U doing parameter domain logons = Yes doing parameter os level = 33 doing parameter preferred master = Yes doing parameter domain master = Yes doing parameter dns proxy = No doing parameter wins support = Yes doing parameter ldap admin dn = "uid=user,cn=admins,cn=relevantcn" doing parameter ldap group suffix = ou=groups doing parameter ldap machine suffix = ou=machines doing parameter ldap passwd sync = Yes doing parameter ldap suffix = dc=domain,dc=com doing parameter ldap user suffix = ou=people doing parameter panic action = /usr/share/samba/panic-action %d pm_process() returned Yes smbldap_search_domain_info: Searching for:[(&(objectClass=sambaDomain)(sambaDomainName=DOMAIN))] smbldap_open_connection: connection opened failed to bind to server ldap://ldap2.domain.net/ with dn="uid=username,cn=admins,cn=thecn" Error: Can't contact LDAP server (unknown) Connection to LDAP server failed for the 1 try! smbldap_open_connection: connection opened failed to bind to server ldap://ldap2.domain.net/ with dn="uid=username,cn=admins,cn=thecn" Error: Can't contact LDAP server etc but I can ping the LDAP server with its hostname and the LDAP alias. I have upped the log level to 10 and grepped for relevant hostnames and things but I am somewhat at a loss as to whats gone wrong, any help you can offer would be very gratefully received. I would also be v happy to post any logs etc to assist.
