Hi, I've upgraded openldap 2.4.57 to 2.4.59 on FreeBSD 12.2 using portmaster, what has always worked over the last few years. After upgrade the config seems to be bad which hasn't changed…? root@openldap2:/usr/local/etc/openldap # /usr/local/libexec/slapd -Tt -u 60d0a1cd PROXIED attributeDescription "O" inserted. 60d0a1cd UNKNOWN attributeDescription "OLCRWMTFSUPPORT" inserted. 60d0a1cd UNKNOWN attributeDescription "OLCRWMNORMALIZEMAPPED" inserted. 60d0a1cd UNKNOWN attributeDescription "OLCRWMREWRITE" inserted. 60d0a1cd config error processing olcOverlay={0}rwm,olcDatabase={-1}frontend,cn=config: slaptest: bad configuration file! dn: olcOverlay={0}rwm objectClass: olcOverlayConfig objectClass: olcRwmConfig olcOverlay: {0}rwm olcRwmTFSupport: false olcRwmNormalizeMapped: FALSE structuralObjectClass: olcRwmConfig olcRwmRewrite: {0}rwm-rewriteEngine "on" olcRwmRewrite: {1}rwm-rewriteMap "ldap" "attr2dn" "ldap://localhost/o=abc.org?dn?sub" olcRwmRewrite: {2}rwm-rewriteContext "bindDN" olcRwmRewrite: {3}rwm-rewriteRule "^eduPersonPrincipalName=[^,]+@[^,]+$" "${ attr2dn($0)}" ":@I" Does anyone have a hint what's going wrong?
