[Bug 1024475] Re: libnss-ldap causes boot hang on Ubuntu 12.04 Precise

[Graham Eames]

Having recently run into this and spent some time debugging it would
appear that one potential cause is if you have edited /etc/ldap.conf and
do not have a new line at the end of the file (so in our case copying a
standard config in as part of a deployment script)

When the libnss-ldap init script is run on shutdown it updates ldap.conf
with the nss_initgroups_ignoreusers directive, but appends it to the end
of the last line in the file rather than putting it on a new line

As such the last line which did read

ldap_version 3

ended up reading

ldap_version 3nss_initgroups_ignoreusers.........

rather than

ldap_version 3
nss_initgroups_ignoreusers..........

By ensuring we have a new line character at the end of the config file,
when the init script runs we end up with the correct content in the file
and the boot completes as expected rather than hanging
