In order to use certificate-based client authentication, you must also enable SSL encryption as described in 7.2.2 Encryption (SSL) Option.
You also have to configure a store administrator. You can use the mail administrator, but it is recommended that you create a unique user ID, such as mmpstore for this purpose so that you can set permissions as needed.
Note that the MMP does not support certmap plug-ins. Instead, the MMP accepts enhanced DNComps and FilterComps property value entries in the certmap.conf file. These enhanced format entries use the form:
mapname:DNComps FROMATTR=TOATTRmapname:FilterComps FROMATTR=TOATTR
So that a FROMATTR value in a certificate’s subjectDN can be used to form an LDAP query with the TOATTR=value element. For example, a certificate with a subjectDN of “cn=Pilar Lorca, ou=pilar, o=siroe.com” could be mapped to an LDAP query of “(uid=pilar)” with the line:
Decide on the user ID you intend to use as store administrator.
While you can use the mail administrator for this purpose, it is recommended that you create a unique user ID for store administrator (for example, mmpstore).
Make sure that SSL encryption is (or will be) enabled as described in 7.2.2 Encryption (SSL) Option.
Configure the MMP to use certificate-based client authentication by specifying the location of the certmap.conf file in your configuration files.
