Hello everyone. I hoped I could ask for a little assistance on an AD / IPA Trust.
I've for a Windows 2008R2 domain. Response Type: LOGON_SAM_LOGON_RESPONSE_EX GUID: e**********************6497 Flags: Is a PDC: no Is a GC of the forest: yes Is an LDAP server: yes Supports DS: yes Is running a KDC: yes Is running time services: yes Is the closest DC: yes Is writable: yes Has a hardware clock: no Is a non-domain NC serviced by LDAP server: no Is NT6 DC that has some secrets: no Is NT6 DC that has all secrets: yes Runs Active Directory Web Services: yes Runs on Windows 2012 or later: no Forest: example.local Domain: example.local Domain Controller: CSAD1.example.local Pre-Win2k Domain: example Pre-Win2k Hostname: CSAD1 Server Site Name : Site1 Client Site Name : Site1 NT Version: 5 LMNT Token: ffff LM20 Token: ffff
----------------- IPA ipa-server-4.4.0-14.el7
Domain = lci.example.com ------------------
I start the process and DNS lookups are working.

[root@ipa-001 samba]# --------------
My bound `ldapsearch` and `kinit` on both domains domain work well.
As I move onto testing the `trust-fetch-domains` area things go bad ( well start to show they are ). -------------- [root@ipa-001 samba]# ipa trust-fetch-domains example.local ------------------------------------------------------------ ---------------------------- List of trust domains successfully refreshed. Use trustdomain-find command to list them. ------------------------------------------------------------ ---------------------------- ---------------------------- Number of entries returned 0 ----------------------------
[root@ipa-001 samba]# ipa trustdomain-find example.LOCAL Domain name: example.local Domain NetBIOS name: example Domain Security Identifier: S-1-5-21-******-857828577-140568808 Domain enabled: True ---------------------------- Number of entries returned 1 ----------------------------
Of course any movement from there on fails. Using other posts I bumped up the logging and pulled out items that I believe assist in this matter. ---------- log.winbindd-dc-connect: check_negative_conn_cache returning result 0 for domain example.local server 192.168.2.3 log.winbindd-dc-connect: check_negative_conn_cache returning result -1073741823 for domain example.local server 192.168.2.2 log.winbindd-dc-connect: check_negative_conn_cache returning result -1073741823 for domain example.local server 192.168.2.4 log.winbindd-dc-connect: get_sorted_dc_list: attempting lookup for name example.local (sitename NULL) log.winbindd-dc-connect: saf_fetch: failed to find server for "example.local" domain log.winbindd-dc-connect: internal_resolve_name: looking up example.local#1c (sitename (null)) log.winbindd-dc-connect: name example.local#1C found. log.winbindd-dc-connect: check_negative_conn_cache returning result -1073741823 for domain example.local server 192.168.2.1 log.winbindd-dc-connect: Adding cache entry with key=[NEG_CONN_CACHE/example.local,192.168.2.3] and timeout=[Thu Jan 1 12:00:00 AM 1970 UTC] (-1497038264 seconds in the past) log.winbindd-dc-connect: check_negative_conn_cache returning result 0 for domain example.local server 192.168.2.3 log.winbindd-dc-connect: check_negative_conn_cache returning result -1073741823 for domain example.local server 192.168.2.2 log.winbindd-dc-connect: check_negative_conn_cache returning result -1073741823 for domain example.local server 192.168.2.4 log.winbindd-dc-connect: get_sorted_dc_list: attempting lookup for name example.local (sitename NULL) log.winbindd-dc-connect: saf_fetch: failed to find server for "example.local" domain log.winbindd-dc-connect: internal_resolve_name: looking up example.local#1c (sitename (null)) log.winbindd-dc-connect: name example.local#1C found. log.winbindd-dc-connect: check_negative_conn_cache returning result -1073741823 for domain example.local server 192.168.2.1 log.winbindd-dc-connect: Adding cache entry with key=[NEG_CONN_CACHE/example.local,192.168.2.3] and timeout=[Thu Jan 1 12:00:00 AM 1970 UTC] (-1497038340 seconds in the past) log.winbindd-dc-connect: check_negative_conn_cache returning result 0 for domain example.local server 192.168.2.3 log.winbindd-dc-connect: check_negative_conn_cache returning result -1073741823 for domain example.local server 192.168.2.2 log.winbindd-dc-connect: check_negative_conn_cache returning result -1073741823 for domain example.local server 192.168.2.4 log.winbindd-idmap: pdb_init_ipasam: support for pdb_enum_upn_suffixes enabled for domain lci.example.local ------------------- I see in the logs the timeouts however I thought they appeared to conflict with the ability to `net ads lookup`.
Any assistance on this would be appreciated a great deal. Thank you so much for your time and looking at this.
