Incorrect host:port combination passed to Dynamic Authenticator

Regarding the libcouchbase Dynamic Authenticator, we have implemented the callbacks -

const char *GetUsername(void *cookie, const char *host, const char *port,

const char *bucket);

const char *GetPassword(void *cookie, const char *host, const char *port,

const char *bucket);

We noticed that cbauth couldn't get the credentials for the host, port provided by the callbacks.

Quoting from the logs attached here,

2018-02-27T03:34:53.474-08:00 [Error] UTIL LCB Failed to get credentials for endpoint: <ud>10.111.170.102:11210</ud>, err: Unable to find given hostport in cbauth database: `10.111.170.102:11210'

We have also collected the lcb_dump and we see the corresponding cluster configuration received by libcouchbase -
