key search X.509 Directory LDAP - directory.comodo.com
I am thinking about recommending comodo as one of the prefered issuer of email certificates for partners and costumers of mine. Therefor I need a possibility to use LDAP key search on directory.comodo.com. I configuered the keyserver like described in http://directory.comodo.com/help/#c (Type: X.509 Directory LDAP / Hostname: directory.comodo.com / Base DN OU=directory, DC=comodo, DC=com / chekced both: Trust keys..., Incude...), but key search fails (LOG: [directory.comodo.com]: error getting recipient encryption key: server open failed).
1. Any idea how to solve this issue? Workaround with other PGP-US searchable LDAP directories which allow upload of public comodo certificates?
2. Any other recommendations (email certificate provider)? despite:
verisign - which had problems with automatic keysearch last year
trustcenter - which is going to be out of business 2014 or so
geotrust - as you can see i don´t want to only recommend symantec subsidiaries l
3. Does anybody know if there is a list of supported keyservers for automatic LDAP keysearch for PGP US? This would be the most valuable information!
Thank you for your help
