thanks Filippo that fixed it … until a reboot when httpd_admin wouldnt come back up which was fixed with reference to one of your posts elsewhere (this error doesnt seem to be spurious because it was observed for 2 separate servers/domains…
[root@cwprod11v02 ~]# /usr/sbin/httpd-admin -f /etc/httpd/admin-conf/httpd.conf
AH00526: Syntax error on line 51 of /etc/httpd/admin-conf/httpd.conf:
SSLCertificateChainFile: file ‘/etc/pki/tls/certs/cwprod11v02-chain.crt’ does not exist or is empty
current remaining error is: Account provider generic error: SSSD exit code 1
In view of the fact this (particular) server is only really being used for mail - i may investigate building the nethserver from scratch, re-creating users by hand and then restoring the emails… im not sure how easily this can be accomplished but 2 days of DR testing / migration work isnt giving me the warm feeling i’d hoped for!
