>          Components: server
>            Reporter: Mohammad Arshad

>             Fix For: 3.5.4, 3.6.0

>
> Currently zookeeper server same field is used to store both user name and password
> Provide a mechanism to separate the user and password either by adding new field or by adding new API
> DETAILS:
> org.apache.zookeeper.data.Id class is used to store scheme and id.
> {code}
> public Id( String scheme, String id)
> {code}
> id field holds only user in most cases but in some cases it holds user as well as password
> By default there are only four authentication provider 
> DigestAuthenticationProvider
> IPAuthenticationProvider
> SASLAuthenticationProvider
> X509AuthenticationProvider
> In code we can check if scheme is digest then {{id.split(":")\[0\]}} is user otherwise id is user. This will work only if we are limited to above four authentication provider
> But Custom authentication provider are very important and are very commonly used. How the zookeeper code will know what is the user, is it id or {{id.split(":")\[0\]}} or anything else ?
> So there is need to add new API which AuthenticationProvider providers implement to define what is user.
