[Pkg-sssd-devel] Bug#1081027: src:sssd: flaky autopkgtest: spawn id exp3 not open

[Andreas Hasenack]

Is d/t/ldap-user-group-krb5-auth also flaky? Because it uses the same
expect script:

d/t/ldap-user-group-krb5-auth:
...
# tests begin here
run_common_tests

# login works with the kerberos password
echo "The Kerberos principal can login on a terminal"
kdestroy > /dev/null 2>&1 || /bin/true
/usr/bin/expect -f debian/tests/login.exp "${ldap_user}"
"${kerberos_principal_pw}" "${ldap_user}"@"${myrealm}"


d/t/ldap-user-group-ldap-auth:
...
# tests begin here
run_common_tests

echo "The LDAP user can login on a terminal"
/usr/bin/expect -f debian/tests/login.exp "${ldap_user}" "${ldap_user_pw}"
