Comment 13 for bug 1557157

bionic verification

First reproducing the problem:
  Version table:
 *** 2.4.45+dfsg-1ubuntu1.5 500
        500 http://br.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages
        500 http://br.archive.ubuntu.com/ubuntu bionic-security/main amd64 Packages
        100 /var/lib/dpkg/status

Command fails:
root@bionic-openldap-saslauthd-1557157:~# ldapsearch -H ldapi:/// -LLL -b 'dc=example,dc=com' -s base -U root -Y PLAIN
SASL/PLAIN authentication started
Please enter your password:
ldap_sasl_interactive_bind_s: Other (e.g., implementation specific) error (80)
 additional info: SASL(-1): generic failure: Password verification failed

And dmesg shows the apparmor denial:
[17283.881912] audit: type=1400 audit(1594228773.536:453): apparmor="DENIED" operation="connect" namespace="root//lxd-bionic-openldap-saslauthd-1557157_<var-snap-lxd-common-lxd>" profile="/usr/sbin/slapd" name="/run/saslauthd/mux" pid=153401 comm="slapd" requested_mask="wr" denied_mask="wr" fsuid=1000111 ouid=1000000

With the updated package from proposed:
  Version table:
 *** 2.4.45+dfsg-1ubuntu1.6 500
        500 http://br.archive.ubuntu.com/ubuntu bionic-proposed/main amd64 Packages
        100 /var/lib/dpkg/status

The ldapsearch command works, and there is no apparmor error in dmesg:
root@bionic-openldap-saslauthd-1557157:~# ldapsearch -H ldapi:/// -LLL -b 'dc=example,dc=com' -s base -U root -Y PLAIN
SASL/PLAIN authentication started
Please enter your password:
