I'm trying to join a Solaris 10 1/13 s10s_u11wos_24a SPARC server to Active Directory 2003. I'm using Samba version 3.6.25 released in August 2016. I can obtain a Kerberos ticket, but the net ads join command fails with a "kinit succeeded but ads_sasl_spnego_krb5_bind failed: NT_STATUS_NOT_SUPPORTED" error. I copied the /etc/crypto/pkcs11.conf file from the global zone to my zone as suggested by Doc ID 1624663.1. I've also tried adding the client ldap sasl wrapping = sign parameter to my smb.conf. I ended up stripping my smb.conf down to basic required parameters, but the error stays the same. Has anyone successfully solved this issue?
