raub@testfirewall:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04 LTS Release: 14.04 Codename: trusty raub@testfirewall:~$ uname -a Linux testfirewall 3.13.0-27-generic #50-Ubuntu SMP Thu May 15 18:06:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux raub@testfirewall:~$ and have before upgrading to 14.04 been using sudo-ldap so network admins can do some work. However, in 14.04, I am seeing raub@testfirewall:~$ sudo pwd sudo: LDAP Config Summary sudo: =================== sudo: uri ldap://kdc.domain.com ldap://kdc2.domain.com sudo: ldap_version 3 sudo: sudoers_base ou=SUDOers,dc=domain,dc=com sudo: binddn (anonymous) sudo: bindpw (anonymous) sudo: bind_timelimit 3 sudo: timelimit 3 sudo: deref 0 sudo: ssl start_tls sudo: tls_cacertfile /etc/ssl/certs/ca-certificates.crt sudo: use_sasl yes sudo: sasl_auth_id (NONE) sudo: rootuse_sasl -1 sudo: rootsasl_auth_id (NONE) sudo: sasl_secprops (NONE) sudo: krb5_ccname FILE:/tmp/host.tkt sudo: =================== sudo: ldap_set_option: debug -> 0 sudo: ldap_set_option: tls_cacertfile -> /etc/ssl/certs/ca-certificates.crt sudo: ldap_set_option: tls_cacert -> /etc/ssl/certs/ca-certificates.crt sudo: ldap_initialize(ld, ldap://kdc.domain.com ldap://kdc2.domain.com) sudo: ldap_set_option: ldap_version -> 3 sudo: ldap_set_option: timelimit -> 3 sudo: ldap_set_option(LDAP_OPT_TIMEOUT, 3) sudo: ldap_set_option(LDAP_OPT_NETWORK_TIMEOUT, 3) sudo: ldap_start_tls_s() ok sudo: sudo_ldap_sasl_interact: SASL_CB_USER Segmentation fault (core dumped) raub@testfirewall:~$ >From syslog: Jun 5 15:16:26 testfirewall kernel: [2068248.457275] sudo[22925]: segfault at 0 ip 00007f2feb02692a sp 00007ffff55073b8 error 4 in libc-2.19.so[7f2feaf9d000+1bc000] That affects both local and network users *and* was observed in a new install and an upgrade from 12.04LTS. Now, if I disable ldap for sudoers in /etc/nsswitch.conf, # sudoers: files ldap sudoers: files I can sudo from a local user with sudo rights.
