I have been playing around with pam_ccreds and I think the bug is in
that package or a configuration mix-up.

Anyway, if I disable shadow lookups via ldap in /etc/nsswitch.conf I got
it to work, otherwise the PAM stack fails with:

authpriv.err su[9407]: pam_acct_mgmt: Authentication failure

which seems to indicate that something is going wrong in the account
(authorisation) part of PAM. I've added debug to pam_unix and pam_ldap
in /etc/pam.d/common-account but neither module seems to be logging
anything.

Without shadow lookups via LDAP at least pam_ldap logs in the account
check that it can't connect to nslcd if it is not running. Also, now
login works (but slow) if nslcd is still running but the LDAP server is
reachable.

Some background on the intricacies of the PAM stack can be found here:
