Title:
  LDAP TLS connection stopped working

Status in gnutls26 package in Ubuntu:
  Incomplete

Bug description:
  My LDAP authentication stopped working with the error: "The signature
  algorithm is not supported"

  This is GNUTLS Error code: -106
  GNUTLS_E_UNSUPPORTED_SIGNATURE_ALGORITHM

  LDAP search reproduces it:

  $ ldapsearch -H ldaps://xxx.xxx.gov/ -b "OU=xxx" -x -d1
  ldap_url_parse_ext(ldaps://xxx.xxx.gov/)
  ldap_create
  ldap_url_parse_ext(ldaps://xxx.xxx.gov:636/??base)
  ldap_sasl_bind
  ldap_send_initial_request
  ldap_new_connection 1 1 0
  ldap_int_open_connection
  ldap_connect_to_host: TCP xxx.xxx.gov:636
  ldap_new_socket: 3
  ldap_prepare_socket: 3
  ldap_connect_to_host: Trying 128.219.164.41:636
  ldap_pvt_connect: fd: 3 tm: -1 async: 0
  TLS: can't connect: The signature algorithm is not supported..
  ldap_err2string
  ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)

  It looks like the SHA1 support was removed from gnutls26...
