Wow, this bug has a long history. I can confirm the issue as well with 4.1.6 and 4.2.1 I've isolated to the line:
auth optional pam_smbpass.so migrate Configured in /etc/pam.d/common-auth That line is added by libpam package installation and also by using pam- auth-update to enable SMB Password Synchronization For 4.2.1 the error however occurs in su: *** Error in `su': double free or corruption (fasttop): 0x000000000110d800 *** Aborted Which happens after the password is entered. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1257186 Title: memory leakage messages (no talloc stackframe) To manage notifications about this bug go to: https://bugs.launchpad.net/samba/+bug/1257186/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
