tcsh-6.15.00-closem.patch removed
    
      This patch was never accepted by upstream since upstream does not like
      the solution: http://mx.gw.com/pipermail/tcsh-bugs/2016-April/001031.html
    
      The issue solved by this patch has been tested on Fedora 23, but
      reproduction was not successful. The package 'nss_ldap' is now obsolote
      (has been retired) and is no longer part of Fedora. It was superseded by
      'nss-pam-ldapd' and 'sssd'. The issue has been most likely mitigated
      with the new identity management used in Fedora (FreeIPA/SSSD).
    
      In case the issue will re-appear, we will need to find work with
      upstream to find a solution which they would be willing to accept.
