Finally got a chance to revisit this after post #29 above. For that servers config I still had a local /etc/passwd entry for the affected account and so was not triggering the described su and sudo symptoms.
On Karmic with: libnss-ldap 261-2.1ubuntu4 sudo 1.7.0-1ubuntu2.1 login 1:4.1.4.1-1ubuntu2 Without an /etc/passwd entry and an otherwise working libnss-ldap setup sudo returns sudo: setreuid(ROOT_UID, user_uid): Operation not permitted and su fails with su: Authentication failure Tests: With libnss-ldap, su and sudo fail. With nscd and libnss-ldap, su and sudo work. With libnss-ldapd, with or without nscd, su and sudo work. As root, getent returns passwd entries correctly for all the above cases. -- NSS using LDAP on Karmic breaks 'su' and 'sudo' https://bugs.launchpad.net/bugs/423252 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libnss-ldap in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
