Description of problem:

When generating a replica file (by running ipa-replica-prepare) with both --dirsrv_pkcs12 and --http_pkcs12. 
Two observations :
- pins provided for these p12 files are not validated, aka, random invalid pins are accepted
- *blank* pin is accepted as well for both p12 files


This was discovered while shanks and myself was testing replication w/ OPTIONS

Version-Release number of selected component (if applicable):
==============
[root@jetfire ~]# rpm -qi ipa-server | head -6

How reproducible:
All the time

Steps to Reproduce:
1. Have a working master IPA instance (host 'jetfire')
2. Prepare replica for host 'ratchet':

We just provided a random password for dirsrv pkcs12 and http pkcs12

Actual results:
Replica gpg file is created w/o any errors despite providing incorrect pins(or no pins)

Expected results:
Passwords for both the p12 files should be validated ; appropriate error should be thrown
