Using CS 9.1 I'm sending SAN nametypes and values in my HTTP requests to the CA inspired by Section A.1.14 below https://access.redhat.com/documentation/en-US/Red_Hat_Certificate_System/... In general this is working, but I seem to be limited to 4 SANs maximum. The CA seems to only process $request_req_san_pattern_<0-3>$ Here's my setup and some logs #### SAN Profile Configuration - 10 SANs #### ... policyset.MySet.SAN.constraint.class_id=noConstraintImpl policyset.MySet.SAN.constraint.name=No Constraint policyset.MySet.SAN.default.class_id=subjectAltNameExtDefaultImpl policyset.MySet.SAN.default.name=Subject Alt Name Extension Default policyset.MySet.SAN.default.params.subjAltNameExtCritical=false policyset.MySet.SAN.default.params.subjAltNameNumGNs=10 policyset.MySet.SAN.default.params.subjAltExtGNEnable_0=true policyset.MySet.SAN.default.params.subjAltExtPattern_0=$request.req_san_pattern_0$ policyset.MySet.SAN.default.params.subjAltExtType_0=$request.req_san_type_0$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_1=true policyset.MySet.SAN.default.params.subjAltExtPattern_1=$request.req_san_pattern_1$ policyset.MySet.SAN.default.params.subjAltExtType_1=$request.req_san_type_1$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_2=true policyset.MySet.SAN.default.params.subjAltExtPattern_2=$request.req_san_pattern_2$ policyset.MySet.SAN.default.params.subjAltExtType_2=$request.req_san_type_2$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_3=true policyset.MySet.SAN.default.params.subjAltExtPattern_3=$request.req_san_pattern_3$ policyset.MySet.SAN.default.params.subjAltExtType_3=$request.req_san_type_3$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_4=true policyset.MySet.SAN.default.params.subjAltExtPattern_4=$request.req_san_pattern_4$ policyset.MySet.SAN.default.params.subjAltExtType_4=$request.req_san_type_4$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_5=true policyset.MySet.SAN.default.params.subjAltExtPattern_5=$request.req_san_pattern_5$ policyset.MySet.SAN.default.params.subjAltExtType_5=$request.req_san_type_5$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_6=true policyset.MySet.SAN.default.params.subjAltExtPattern_6=$request.req_san_pattern_6$ policyset.MySet.SAN.default.params.subjAltExtType_6=$request.req_san_type_6$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_7=true policyset.MySet.SAN.default.params.subjAltExtPattern_7=$request.req_san_pattern_7$ policyset.MySet.SAN.default.params.subjAltExtType_7=$request.req_san_type_7$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_8=true policyset.MySet.SAN.default.params.subjAltExtPattern_8=$request.req_san_pattern_8$ policyset.MySet.SAN.default.params.subjAltExtType_8=$request.req_san_type_8$ policyset.MySet.SAN.default.params.subjAltExtGNEnable_9=true policyset.MySet.SAN.default.params.subjAltExtPattern_9=$request.req_san_pattern_9$ policyset.MySet.SAN.default.params.subjAltExtType_9=$request.req_san_type_9$ #### Parsing from HTTP Request - SAN0 to SAN4 are received at the CA from client ##### ...

What's interesting is the SubjectAltNameExtDefault can take several extra hardcoded nametypes and values from the profile and populate them in the enrolled certificate. Any thoughts? Thanks GW
