Comment 2 for bug 1295184

The dpkg log shows the installation of nslcd (was uninstalled before). The relevant part shows that adduser failed:

Adding new user `nslcd' (UID 116) with group `nslcd' ...
adduser: `/usr/bin/chfn -f nslcd name service LDAP connection daemon nslcd' exited from signal 139. Exiting.
dpkg: error processing nslcd (--configure):
 subprocess installed post-installation script returned error exit status 1

The kernel log shows:

[11508.391940] chfn[10880]: segfault at 10 ip 00007f090734df90 sp 00007fffe7854230 error 4 in pam_krb5.so[7f0907348000+c000]

Which seens to point to a bug in pam_krb5 or one of it's libraries.

While you could use pam_krb5 and pam_ldap together, it is probably not what you want.
