TPS External Registration Multiple Key Sets
Currently, in the case of non-externalReg, we use the filtering system that processes a set of mappings such as following to resolve the tokenType (tps profile):
op.enroll.mapping.0.filter.appletMajorVersion=1 op.enroll.mapping.0.filter.appletMinorVersion= op.enroll.mapping.0.filter.tokenATR= op.enroll.mapping.0.filter.tokenCUID.end= op.enroll.mapping.0.filter.tokenCUID.start= op.enroll.mapping.0.filter.tokenType=userKey op.enroll.mapping.0.target.tokenType=userKey op.enroll.mapping.1.filter.appletMajorVersion= op.enroll.mapping.1.filter.appletMinorVersion= op.enroll.mapping.1.filter.tokenATR= op.enroll.mapping.1.filter.tokenCUID.end= op.enroll.mapping.1.filter.tokenCUID.start= op.enroll.mapping.1.filter.tokenType=soKey op.enroll.mapping.1.target.tokenType=soKey op.enroll.mapping.2.filter.appletMajorVersion= op.enroll.mapping.2.filter.appletMinorVersion= op.enroll.mapping.2.filter.tokenATR= op.enroll.mapping.2.filter.tokenCUID.end= op.enroll.mapping.2.filter.tokenCUID.start= op.enroll.mapping.2.filter.tokenType= op.enroll.mapping.2.target.tokenType=userKey op.enroll.mapping.order=0,1,2
The keySet is determined by the following configuration:
... conn.tks1.keySet=defKeySet ...
When multiple keySets are desired, one is expected to define multiple sets of conn.tks entries, e.g.
... conn.tks2.keySet=jForte ...
TPS Profiles will then point to the "conn.tks" that defines the desired keySet. e.g.
op.enroll.delegateIEtoken.tks.conn=tks1
In the case of externalReg, however, the above filtering system is completely bypassed and instead it retrieves the tokenType from the user record. This presents a challenge when in an environment where multiple vendor cards are supported where keySets are to be different. When a user’s ldap record is populated with a set tokenType, it does not know which card will end up doing the enrollment, and therefore keySet cannot be predetermined.
We can extend the existing GetTokenType filtering system to support resolving keySet. Currently the function signature looks like this:
bool RA_Processor::GetTokenType(const char *prefix, int major_version, int minor_version,
const char *cuid, const char *msn, NameValueSet *extensions,
RA_Status &o_status /* out */, const char *&o_tokenType /* out */)
It is cleaner to let externalReg have its own set of filtering config params. So, instead of "op.enroll.", we will replace the prefix with "externalReg."when calling. Since "prefix" is already one of the parameters, it does not require changes to the function as far as prefix is concerned. The following is one way to do it:
-
change the name GetTokenType to something like ProcessMappingFilter
-
in the now ProcessMappingFilter function, we have to make the tokenType-specific code generic enough to work for both tokenType and keySet. Here is a sample function that I changed from the existing GetTokenType(). Note: This is meant for giving an idea of the design only, it is by no means complete or efficient.
/*
* Determine the selection by processing through a set up mapping rules.
* Admin can set up mapping rules in the config file which allow different
* operations depending on the CUID, apple tversion, ATR, etc.
* This method is currently intended for making Token Type or Key Set
* selection.
*/

}
-
in the code where RequestUserId() and AuthenticateUser() are called under isExternalReg, we add a call to the new function ProcessMappingFilter() to resolve the keySet.
-
wherever keySet is retrieved, e.g.
PR_snprintf((char *)configname, 256, "conn.%s.keySet", connid);
const char *keySet = RA::GetConfigStore()->GetConfigAsString(configname);
we use the keySet resolved from ProcessMappingFilter()
Here is an example instruction on how to test this feature, once implemented:
The above sample code did not provide a separate config parameter for this feature, so let’s just assume the isExternalReg parameter is the trigger as sample indicated above:
-
make sure ldap is setup, and all config in place and set correctly
-
turn on isExteranalReg
-
add the externalReg.mapping.X.target.Y=Z parameters like the op.enroll. ones, with the following exceptions (instead of tokenType, you do keySet):
-
externalReg.mapping.X.target.keySet=<selected keySet name supported on tks>
-
externalReg.mapping.X.filter.keySet=<selected keySet name supported on tks>
-
-
make sure you specify a cuid range that your card(s) will fall into
-
restart server
-
if you have all the supported actual physical smart cards, then you can just try to format and enroll
-
if you are testing with tpsclient, you need to add extra extension keySet and leave out the tokenType . e.g.:
-
op=ra_enroll uid=user2a num_threads=1 pwd=netscape new_pin=netscape extensions=keySet=defKeySet
-
also make sure your cuid fall into the cuid range filter that you intend it to fall into
