A system for distributed database management as described in claim 1, wherein said distributed database manager further comprises: a list of network elements each having an out-of-band port, a security gate thereto, and a database receptor; and, a polling program therewithin having the ability to step through said list of network elements and replace the security database with an updated security database. 3. A system for distributed database management as described in claim 2, wherein each said security database comprises: a transaction register to record data of access request, grants, and denials; and, wherein said polling program further comprises: a data collection portion for receiving said record data from said transaction register at the time the security database is updated and for, upon receiving the data from the register, resetting he register to zero. 4. A system for distributed database management as described in claim 3, wherein said polling program further comprises: a failure monitoring portion wherein each network element beyond the reach of said communication program is identified. 5. A system for distributed database management as described in claim 4, wherein said distributed database manager further comprises: a report program to format the data received from said data collection portion and said failure monitoring portion. 6. A system for distributed database management as described in claim 1 wherein said distributed database manager further comprises: a communication program therewithin with the default setting of an in-band connection to the security database; and, said communication program, in turn, further comprising a communication channel selector to change to an out-of-band connection to the security database. 7. A system for distributed database management as described in claim 1, wherein said distributed database manager further comprises: a communication program therewithin the out-of-band setting of an in-band connection to the security database; and, said communication program, in turn, further comprising a communication channel selector to change to an in-band connection to the security database. 8. A system for distributed database management as described in claim 1, wherein said plurality of databases are an interrelated hierarchical series of authentication data with each successive one of said databases being more restrictive as to the accessibility of the network elements by said remote users. 9. A distributed database management device serving network elements of a wide area network having, for in-band access by a remote user a centralized security system, said distributed database management device comprising: a central processing unit (CPU); a list of network elements within said CPU each having an out-of-band port, a security gate thereto, and a database receptor; a plurality of interrelated hierarchical series of authentication data within
