Hi all, I've been struggling to setup a centralized authentication system for quite some time. It is composed by: - openldap 2.4.43, with TLS self-signed certs (root chain is ok): ldaps://serv; - pam 1.2.1; pambase 20150213; - sssd 1.13.1; - openssh 7.1. Currently I'm trying to authenticate a LDAP user in the server that hosts openldap. ldapsearch -x shows me stuff correctly, with TLS working. If I try to connect through the command-line, the logs show sssd getting stuff from openldap with success. But, login fails: <log> login[xxxx]: pam_sss(login:auth): authentication success; logname=LOGIN uid=0 euid=0 tty=/dev/tty1 ruser= rhost= user=user_a login[xxxx]: FAILED LOGIN (1) on '/dev/tty1' FOR 'UNKNOWN', Authentication failure </log> Also, id user_a fails, getent passwd user_a fails. Have no idea what may be wrong (if sssd, ldap DB, whatever). sssd.conf [sssd] config_file_version = 2 services = pam domains = LDAP debug_level = 4 [nss] [pam] debug_level = 5 [domain/LDAP] debug_level = 4 id_provider = ldap auth_provider = ldap access_provider = ldap cache_credentials = false ldap_uri = ldaps://server ldap_schema = rfc2307 ldap_search_base = dc=casa,dc=lan ldap_id_use_start_tls = true ldap_tls_cacert = /etc/openldap/ssl/cacert.pem ldap_tls_cacertdir = /etc/openldap/ssl ldap_tls_reqcert = demand tls_reqcert = demand ldap_user_search_base = ou=People,dc=casa,dc=lan ldap_user_home_directory = homeDirectory ldap_user_shell = loginShell ldap_group_search_base = ou=Group,dc=casa,dc=lan ldap_access_filter = memberOf=ou=People,dc=casa,dc=lan # Leave this as password ldap_default_authtok_type = password system-auth auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass #auth requisite pam_succeed_if.so uid >= 500 quiet auth sufficient pam_sss.so use_first_pass auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so #account sufficient pam_succeed_if.so uid < 500 quiet #account [default=bad success=ok user_unknown=ignore] pam_sss.so #account [default=bad success=ok] pam_sss.so account sufficient pam_sss.so account required pam_permit.so nsswitch.conf passwd: compat sss shadow: compat sss group: compat sss hosts: files dns networks: files dns services: db files protocols: db files rpc: db files ethers: db files netmasks: files netgroup: files bootparams: files automount: files aliases: files Thanks in advance!
