@dresswithpockets commented on GitHub (Mar 13, 2018):

I solved this. The problem was that there are multiple entries in the passwd file that match the default/no bucket.

Ultimately the confusion from this issue came from the fact that the error message is not very helpful. I managed to decipher what the error message meant by looking at the code that leads to that message:

if(resmap.end() != resmap.find(bucket)){ // this line helped me understand what the message meant.
      S3FS_PRN_EXIT("same bucket(%s) passwd setting found in passwd file.", ("" == bucket ? "default" : bucket.c_str()));
      return -1;
}

I'm going to submit a PR for this issue to make this message more descriptive and helpful.
