Thanks Thanks for the tip with the proper debug syntax - I was unable to get a single log item out of sudo before. I think I have found something. This is the relevant part of the output of all@debug (you need this not trace I think): Sep 14 22:13:39 sudo[2314] username=doma Sep 14 22:13:39 sudo[2314] domainname=NULL Sep 14 22:13:39 sudo[2314] state |= USERMATCH Sep 14 22:13:39 sudo[2314] Received 1 rule(s) Sep 14 22:13:39 sudo[2314] -> sudo_sss_filter_result @ ./sssd.c:175 Sep 14 22:13:39 sudo[2314] in_res=0xb7c9c1b8, count=1, act=INCLUDE Sep 14 22:13:39 sudo[2314] emalloc: cnt=1 Sep 14 22:13:39 sudo[2314] -> sudo_sss_result_filterp @ ./sssd.c:648 Sep 14 22:13:39 sudo[2314] -> sudo_sss_check_host @ ./sssd.c:556 Sep 14 22:13:39 sudo[2314] val[0]=nappali.szilva Sep 14 22:13:39 sudo[2314] -> addr_matches @ ./match_addr.c:206 Sep 14 22:13:39 sudo[2314] -> addr_matches_if @ ./match_addr.c:61 Sep 14 22:13:39 sudo[2314] <- addr_matches_if @ ./match_addr.c:71 := false Sep 14 22:13:39 sudo[2314] IP address nappali.szilva matches local host: false @ addr_matches() ./match_addr.c:217 Sep 14 22:13:39 sudo[2314] <- addr_matches @ ./match_addr.c:218 := false Sep 14 22:13:39 sudo[2314] -> netgr_matches @ ./match.c:941 Sep 14 22:13:39 sudo[2314] netgroup appali.szilva has no leading '+' Sep 14 22:13:39 sudo[2314] <- netgr_matches @ ./match.c:953 := false Sep 14 22:13:39 sudo[2314] -> hostname_matches @ ./match.c:776 Sep 14 22:13:39 sudo[2314] host nappali matches sudoers pattern nappali.szilva: false @ hostname_matches() ./match.c:788 Sep 14 22:13:39 sudo[2314] <- hostname_matches @ ./match.c:789 := false Sep 14 22:13:39 sudo[2314] sssd/ldap sudoHost 'nappali.szilva' ... not Sep 14 22:13:39 sudo[2314] <- sudo_sss_check_host @ ./sssd.c:591 := false Sep 14 22:13:39 sudo[2314] <- sudo_sss_result_filterp @ ./sssd.c:654 := 0 Sep 14 22:13:39 sudo[2314] reallocating result: 0xb7cb1900 (count: 1 -> 0) Sep 14 22:13:39 sudo[2314] <- sudo_sss_filter_result @ ./sssd.c:221 := 0xb7c9e410 Sep 14 22:13:39 sudo[2314] u_sss_result=(0xb7c9c1b8, 1) => f_sss_result=(0xb7c9e410, 0) Sep 14 22:13:39 sudo[2314] <- sudo_sss_result_get @ ./sssd.c:728 := 0xb7c9e410 Sep 14 22:13:39 sudo[2314] searching SSSD/LDAP for sudoers entries Sep 14 22:13:39 sudo[2314] Done with LDAP searches And here is the code from match.c. bool hostname_matches(const char *shost, const char *lhost, const char *pattern) { debug_decl(hostname_matches, SUDO_DEBUG_MATCH) const char *host; bool rc; host = strchr(pattern, '.') != NULL ? lhost : shost; if (has_meta(pattern)) { rc = !fnmatch(pattern, host, FNM_CASEFOLD); } else { rc = !strcasecmp(host, pattern); } sudo_debug_printf(SUDO_DEBUG_DEBUG|SUDO_DEBUG_LINENO, "host %s matches sudoers pattern %s: %s", host, pattern, rc ? "true" : "false"); debug_return_bool(rc); } By the look of it it should match. I tried to find out how shost and lhost get their values - these are macros to a member of the sudo_user struct but that part is not debugged. Only thing I can confirm is that I do not get the log_warning(MSG_ONLY, N_("unable to resolve host %s"), user_host); from line 816 of sudoers.c. I also checked the hosts file and there I do have the 192.168.110.3 nappali nappali.szilva entry. Still stuck whit this.
