It's on Centos 8 with: ipa-server-4.9.6-10.module_el8.5.0+1055+c415bbe9.x86_64 sssd-ipa-2.5.2-2.el8_5.3.x86_64 krb5-libs-1.18.2-14.el8.x86_64 I've tried higher 'debug_level' for other bits in '/etc/sssd/sssd.conf' but there it nothing 'abnormal' there - or I've gone blind. All & any suggestions on how to troubleshoot/fix this very much appreciated. many thanks, L.
