Public bug reported:

Binary package hint: libnss-ldap

This is a report and manual work around:

Installed info:
Jaunty on an NSLU2 ARM 
Description:	Ubuntu 9.04
Release:	9.04
2.6.28-11-ixp4xx armv5tel

ii  libnss-ldap                       261-2.1ubuntu1                    NSS module for using LDAP as a naming service

Looks like the build for the armel (NSLU2 specifically)  provides an incomplete symlink'd or unfinished build which doesn't allow LDAP user accounts to operate locally. A Ubuntu Jaunty i686 client with libnss_ldap installed and configured to use the NSLU2 servers works ok, but other remote NSLU2 don't.

All 'getent passwd' operation executed on NSLU2 (local or remote) only
list local accounts. Jaunty  i686 to NSLU2 'getent passwd' works.

Found on NSLU2 that a library symlink in /usr/lib/libnss_ldap.so
referenced a non-existant /lib/libnss_ldap.so.2

lrwxrwxrwx root/root         0 2008-11-19 08:32 ./usr/lib/libnss_ldap.so -> /lib/libnss_ldap.so.2
root at J-SLUG00:/lib# find /lib/*nss*ldap* -ls 
382776    0 lrwxrwxrwx   1 root     root           13 Jun 12 15:54 /lib/nss_ldap.so -> nss_ldap.so.1
382775   80 -rw-r--r--   1 root     root        76028 Nov 19  2008 /lib/nss_ldap.so.1
root at J-SLUG00:/lib# 

There exists a file called /lib/nss_ldap.so.1,  compared the entry
points with a Jaunty i686 build libnss_ldap.so.2 and they match.

Manual installed workaround solution:
  Create a symlink for libnss_ldap.so.2 -> nss_ldap.so.1 in /lib

root at J-SLUG00:/ # getent passwd | grep john
root at J-SLUG00:/ # cd /lib
root at J-SLUG00:/lib# 
root at J-SLUG00:/lib# ln -s nss_ldap.so libnss_ldap.so.2
root at J-SLUG00:/lib# getent passwd | grep john
john:x:1000:10000:John Doe:/home/john:/bin/bash
root at J-SLUG00:/lib# 

Build logfile for ARM shows the build kit problem:

drwxr-xr-x root/root         0 2008-11-19 08:32 ./lib/
-rw-r--r-- root/root     76028 2008-11-19 08:31 ./lib/nss_ldap.so.1
lrwxrwxrwx root/root         0 2008-11-19 08:32 ./usr/lib/libnss_ldap.so -> /lib/libnss_ldap.so.2
lrwxrwxrwx root/root         0 2008-11-19 08:32 ./lib/nss_ldap.so -> nss_ldap.so.1
