[Backport MB-25103] - Authentication Fails When Colon Character ":" Exists in Password

One of our prospects working with PHP SDK found a potential bug.  He tried a password with a colon (":") character, and it doesn't seem to work from a test PHP script.

Steps to reproduce:

• Create a user with at least "read" permissions to a bucket and a password with a ":" character.  For this test, I created "admin" user with "zzz:zzz" password on 'travel-sample' bucket.

- Try running a N1QL query against the bucket via N1QL REST API.  Here is a URL to test from Postman app for Chrome or similar REST client:

http://127.0.0.1:8093/query/service?statement=select%20a.name%2Cr.destinationairport%2C%20count(a.name)%20total_flights%20from%20%60travel-sample%60%20r%20join%20%60travel-sample%60%20a%20on%20keys%20r.airlineid%20where%20r.type%20%3D%22route%22%20and%20a.type%3D%22airline%22%20group%20by%20r.destinationairport%2C%20a.name%20order%20by%20r.destinationairport&creds=[{"user":"admin","pass":"zzz:zzz"}

- Try reading from the same bucket with a PHP script.  Below is the sample script:

<?php

#$cluster = new CouchbaseCluster("couchbase://10.211.55.2"); # Connect from Parallels Desktop VM

$cluster = new CouchbaseCluster("couchbase://127.0.0.1"); # Connect from Parallels Desktop VM

#$cluster->authenticateAs("admin1", "password");

$cluster->authenticateAs("admin", "zzz:zzz");

$bucket = $cluster->openBucket('travel-sample');

$query = CouchbaseN1qlQuery::fromString('SELECT `name` FROM `travel-sample` WHERE `name` IS NOT NULL LIMIT 10');

$result = $bucket->query($query);

foreach ($result->rows as $row)

{

    var_dump($row);

}

?>
