[Pki-users] Rewrite of Subject in profile

Hi and good morning. I get some request from mobile devices which are very poor. Subject: CN=B1C43CD0-1624-5FBB-8E54-34FG17DFD3A1\x00 With this subject name, it is not possible to enroll a certificate, because of the " \x00" at the end.. So i'm compelled to rewrite the Subject name. In the first way I only want to remove the "\x00" characters from CN. I've tried some pattern and configs, but it doesn't work. Does one of you knows how this could work? policyset.cmcUserCertSet.1.constraint.class_id=subjectNameConstraintImpl policyset.cmcUserCertSet.1.constraint.name=Subject Name Constraint policyset.cmcUserCertSet.1.constraint.params.accept=true policyset.cmcUserCertSet.1.constraint.params.pattern=.* policyset.cmcUserCertSet.1.default.class_id=userSubjectNameDefaultImpl policyset.cmcUserCertSet.1.default.name=Subject Name Default policyset.cmcUserCertSet.1.default.params.name=.*CN=................................... In the second way, i want to set the whole subject like this below. But I want to use the CN which comes in the csr. Subject: C=AT, ST=Vienna, L=Vienna, O=My Company GmbH, OU=MYORGUNIT, CN=mycn.example.com /emailAddress=pki-AT-example.com Thanks for your help. BR Florian
