Thanks a lot. I intend to use it mostly as a SIP user directory. For the
dial-plan I dont mind parsing and syncing XML file across servers (if
there were a small cluster). The main deal is AUTHENTICATION. The
authentication scheme I wish to keep is Kerberos (with SASL in Ldap for
binding). This way all my credentials are centralized, be it SIP or
mail.
This would be a great achievement for me and many enterprises having
thousands of identities. The dialplan stays fairly static once developed
so I dont mind that being in a XML file. The dynamic stuff (user
credentials) I wish to keep in a centralized store such as LDAP.
