[Bug 423252] Re: NSS using LDAP on Karmic breaks 'su' and 'sudo'

Since 8.10 (Intrepid), the Ubuntu Server Guide section regarding LDAP
authentication references the auth-client-config and libnss-ldap
packages.  However, following these instructions when using LDAP with
TLS breaks various authentication functions in 9.10 (Karmic).  After
determining this issue still exists (nearly 7 months later) in the beta
release of 10.04 (Lucid), I began looking for new workarounds.  I found
a package first available in Karmic, nslcd, which also installs libnss-
ldapd, nscd, and several other dependencies.  All of the latter packages
exist in the 'universe' component.  I removed the nscd package for
testing purposes.  Using the configuration provided in the opening post
for this bug report, 'su' and 'sudo' now function properly.  Although
I'm still unsure as to the exact origin of this issue (e.g., eglibc,
libnss-ldap, sudo, etc.), replacing libnss-ldap with libnss-ldapd
probably provides the core of this workaround.
