[Samba] Failed to prepare gensec: NT_STATUS_INVALID_SERVER_STATE

I'm also having a bit hard time to read it, but i did notice at least these.

Question for me also is, is this an AD-DC or Member server. 
Looks like its AD-DC.  
 
/etc/krb5.conf  ( this is, in a normal setup ) 
[libdefaults]
        default_realm = AD.BIB.LAN

# The following krb5.conf variables are only for MIT Kerberos.
        kdc_timesync = 1
        ccache_type = 4
        forwardable = true
        proxiable = true

# Sufficient. ( thats the default krb5.conf at install, if REALM is supplied.

/etc/nsswitch.conf 
passwd:> > files systemd winbind group: files systemd winbind shadow: files
> > gshadow: files hosts: files mdns4_minimal [NOTFOUND=return] dns
> > networks: files protocols: db files services: db files ethers: db
In the hosts line 
Change this line : hosts: files mdns4_minimal [NOTFOUND=return] dns  
To
hosts: files dns mdns4_minimal [NOTFOUND=return]


/etc/samba/smb.conf 
refresh tickets = yes 
dedicated keytab file = /etc/krb5.keytab
kerberos method = secrets and keytab 

These should not be set for an AD-DC, (as far i know).

[Samba] Fwd: Failed to prepare gensec: NT_STATUS_INVALID_SERVER_STATE

I will try again with a different email client, plain text only and keep 
my fingers crossed.....

My logging is flooded with these notifications:

the list of names that may not be used for top-level domains the following
labels:

.local
.localdomain
.domain
.lan
.home
.host
.corp

Now, note that .lan is in there.. But.. Its not that a big problem..

If you config nsswitch.conf correctly (better) or if you enable 
publish-resolv-conf-dns-servers in avahi-daemon.conf. 
the file /etc/resolv.conf will be read, too.

What i removed from the debug output, like Rowland also said, all good.

All you need here is : 
[libdefaults]
        default_realm = AD.BIB.LAN

# The following krb5.conf variables are only for MIT Kerberos.
        kdc_timesync = 1
        ccache_type = 4
        forwardable = true
        proxiable = true

The rest are default settings.

OR enable publish-resolv-conf-dns-servers in avahi-daemon.conf  
And keep as is, or dont and change to this. (moved dns more to front)
hosts: files dns mdns4_minimal [NOTFOUND=return]

Use getent passwd username to see of its all ok.

What are your clients to this DC? Windows 7 with latest rollup? If so, 
this might be the same as bug #14867.

[Samba] Failed to prepare gensec: NT_STATUS_INVALID_SERVER_STATE

I'm seeing the same issue since updating to 4.13 on my Ubuntu system and 
I have done additional debugging and reported an issue for the Ubuntu 
package at https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1951490.

To sum it up here aswell:

Enabling debug logs show that this is caused by the ownership of a 
directory which samba complains is not matching:

[2021/11/19 01:48:37.482365, 4, effective(30000XX, 100), real(30000XX, 
0)] 
../../source3/rpc_server/rpc_ncacn_np.c:110(make_internal_rpc_pipe_socketpair)
 ? Create of internal pipe \pipe\spoolss requested
[2021/11/19 01:48:37.485785, 3, effective(30000XX, 100), real(30000XX, 
0)] ../../lib/util/util.c:483(directory_create_or_exist_strict)
 ? directory_create_or_exist_strict: invalid ownership on directory 
/var/lib/samba/private/msg.sock
[2021/11/19 01:48:37.485807, 1, effective(30000XX, 100), real(30000XX, 
0)] ../../source3/auth/auth_samba4.c:248(prepare_gensec)
 ? imessaging_init failed

The issue is caused by /var/lib/samba/private/msg.sock being owned by 
root:root in my case (and it gets created with those permissions aswell 
if I delete it), but 
https://github.com/samba-team/samba/blob/db11778b57610e24324aa4342f89918f66157d71/source4/lib/messaging/messaging.c#L507
uses geteuid() which is sometimes the user ID of the connecting user (as 
can be seen above, XX is the number that represents the uid of the 
windows user connecting).

I am not sure if this is related to my "unable to print"-issue but
this
happens whenever I try to print and whenever the print queue is 
refreshed by a client.
