Use DEEPBIND to load the nss modules. Helps thunderbird (linked against its
|
|
own version of the ldap libs) when using nss_ldap (linked against system
|
|
libldap) leading to crashes due to incompatibilities.
|
|
|
|
This has a downside: Linking against libraries overriding malloc() and free()
|
|
will break (unless the malloc()'d pointers by glibc are free()able by these).
|
|
This is fixable in principle, just needs some work.
