Comment 3 for bug 110278

As per the /usr/share/doc/gq/README.Debian it suggests you manually create your configuration file as there is a known issue with connecting to your ldap server.
And your server configuration disappearing.

I manually edited my ~/.gq file to contain the following <ldapserver> section.

    <ldapserver>
        <name>LDAP Server</name>
        <ldaphost>ldaps://ldapmaster.foo.domain.tld</ldaphost>
        <ldapport>389</ldapport>
        <basedn>dc=domain,dc=net,dc=au</basedn>
        <binddn>cn=Manager,dc=domain,dc=net,dc=au</binddn>
        <search-attribute>cn</search-attribute>
        <ask-pw>True</ask-pw>
        <pw-encoding>Base64</pw-encoding>
    </ldapserver>

Originally my <ask-pw> section was set to False, and there was no <pw-encoding> section.
Add these and restart gq, you client should now connect successfully. (Mine did anyway)
