Package: libgnutls26 Followup-For: Bug #810814 Hi,
I can confirm that the addition of 'SECURE256' in the cipher suites configuration seems to be the problem, switching from olcTLSCipherSuite: SECURE256:!ARCFOUR-128:!3DES-CBC:-VERS-SSL3.0 to olcTLSCipherSuite: NORMAL:!ARCFOUR-128:!3DES-CBC:-VERS-SSL3.0 worked for me, but is of course not ideal. Debugging with gnutls-cli yields the same results as in the related Ubuntu bug report https://bugs.launchpad.net/ubuntu/+source/gnutls26/+bug/1534230 i.e. 'SECURE256' doesn't work, while 'SECURE256:+SIGN-ALL' does work with gnutls-cli (but unfortunately the +SIGN-ALL doesn't help when configuring slapd's olcTLSCipherSuite).
