Thanks. This package is linked with GnuTLS, not OpenSSL.

I don't have an Ubuntu install handy, but on Debian 7 (wheezy), which also ships 2.4.31, I get:

modifying entry "cn=config"
ldap_modify: Inappropriate matching (18)
	additional info: modify/add: olcTLSCACertificateFile: no equality matching rule

My suggestion is: when replacing the values, either delete the existing values before adding the new ones, or use 'replace:' instead of 'add:' to have that done for you.

If you have the time, I would also be interested to know whether you encounter the same segfault using Ubuntu 15.10, or the 14.04 backport from my PPA:


Sorry but I'm having some trouble providing a backtrace due to the
complexity of the ldap command.

I just realized it wouldn't be much help anyway, since the packages you have installed don't include debug symbols for the ldap* clients, but for the record, appropriate commands would have been:

apt-get install libldap-2.4-2-dbg
gdb --args ldapmodify -H ldapi:// -Y EXTERNAL -f addcerts.ldif
