[Samba] new dc does not allow login..?

[Joachim Lindenberg]

In installed a new DC (Samba 4.12.8 on Ubuntu 20.4) and initially everything appeared to work smoothly. Now I experience issues:

 

DCDIAG /s:cobra.samba.lindenberg.one

 

Directory Server Diagnosis

 

Performing initial setup:

   [cobra.samba.lindenberg.one] LDAP bind failed with error 1326,

   The user name or password is incorrect..

 

With the other DC (still samba 4.11.14 on Ubuntu 18.4) many test succeed, but replication is obviously stuck due to the authentication issue.

On both DCs, of course with different names and ids.

 

Please advise.

Thanks, Joachim
