autofs-5.1.8 - improve handling of ENOENT in sss setautomntent() From: Ian Kent In the sss lookup module function setautomntent() a return of ENOENT isn't handled quite right. If ENOENT (rather than EHOSTDOWN) is returned from sss setautomntent() we should assume the LDAP info. has been read by sss and the entry in fact doesn't exist.
