[Bug 874307] Re: many applications fail, general protection with LDAPS in libgcrypt on 11.10

[Fridtjof Busse]

Is there a workaround for this problem? Right now, oneiric i386 is completly broken for us (we deploy several dozen desktops).
x86_64 seems to work, but poses different problems with plugins, migration etc.
And yes, we need LDAP authentication.

Title:
  many applications fail, general protection with LDAPS in libgcrypt on
  11.10

Status in “libgcrypt11” package in Ubuntu:
  New

Bug description:
  If I configure nsswitch.conf to use ldap, and have an ldaps uri in
  /etc/ldap.conf, then libgcrypt segfaults for any application that
  requires it:

  Turning the encryption off in the ldap connection (ie, replacing
  ldaps:// with ldap://) causes the problem to stop.
