Hello all, Using openssl, I can create CA certificate by using the linux command line. But this thing I want to do using PHP that is I want to add some information in the openldap regarding a user and also would like to insert his public key certificate along with the other information. Can you please suggest any link or documentation on this topic. For your information I can insert information like user,email,phone,email in openldap but haven't tried to insert the certificate in openldap yet. The issue is, I want to make the whole process automated like all user information user will input in a form and upon clicking submit button all those information along with his certificate which will be generated then and there will be inserted in openldap. Thanks in advance.
