Package: libnss-ldap
Version: 238-1sarge1
Severity: important
*** Please type your report below this line ***
After upgrading to version 238-1sarge1, backuppc is no longer working.
After investigating a bit, it seems that it is no longer possible to use
fork inside perl (the child process does not execute properly). Having
into account that the security fix deals with a race condition using fork,
it seems that there is a connection.
It seems (although I am not completely sure) that the child process dies
just after the creation before executing any line. For example, I include
below
the strace output for one of these children.
Installing again the older version solves all the problems.
Thanks.
Regards.

I'm going through all the libnss-ldap bugs in order to clean up the list
and try to address most of the remaining issues.
As such, this bug is against a version of libnss-ldap that will no
longer receive updates so is unlikely to be fixed.
If you can reproduce the problem with a recent version of libnss-ldap,
feel free to re-open this bug or file a new one.
Thanks,
