How One-way Trust works - MIT KDC to Active Directory

[#1]

I read the article 

But I can't understand a few things

1. I have
a Hadoop (3.1.3)
MIT KDC cluster on a separate server
Active Directory for
server users with hadoop is not included in the domain

2. All hadoop NN, DN, JN, etc. services are launched using the keytabs created for them and are working successfully

3. any requests from the user from AD fall with an error

single-party trust between AD and MIT KDC is set up
I can't understand what algorithm works in this scheme for users in AD through kinit they get a ticket to AD, but how do they get into hadoop, which works with MIT KDC tickets?
It turns out that after authentication via kinit in AD, they should receive a ticket to MIT KDC somehow? or does this ticket get a NameNode for them , for example?
Can someone explain how this mechanism works?

traffic analysis shows an error

KRB5KDC_ERR_S_PRINCIPAL_UNKNOWN

requests to dfs from a user in MIT KDC are successfully executed

Checking

./hdfs groups

returns the correct set of groups

but the AD user's requests after kinit return the above error

[#4 · Accepted solution]

the problem was in trust - the password was incorrectly set in the MIT KDC when creating the trust

[#5]

The password is correct but the same problem occurs
