Notes about Debian's libldap2 package
-------------------------------------

It has been reported that using libnss-ldap can cause a failure to 
unmount /usr on system shutdown. The reason is that the nss module
uses libldap from /usr and is used by the shell in the system 
scripts executed on shutdown/reboot. 

More precisely bash uses the getpwuid function to get the data of
the current user which pulls in the nss modules which includes
the ldap libraries if you are using that module. 

Possible solutions to this problem are:

a) use another shell that does not utilize getpwuid for getting info
   about the current user (take dash for example).
b) make sure that the nsswitch.conf is replaced by a version which does
   not mention ldap before the system is shut down (and have a startup
   script that installs the "full" version of that file).
c) move the libraries to /lib (not recommended).
