We encountered a compilation issue in the v4-22-stable branch due to the following commit made approximately two months ago:
 
https://gitlab.com/samba-team/samba/-/commit/83c60df6e8dd604c4954e1b444b8d2332dbff62b
 
In this commit, the file source3/libads/kerberos_keytab.c uses the function smb_krb5_parse_name_flags, which is specific to HEIMDAL.
This function internally relies on the flag KRB5_PRINCIPAL_PARSE_NO_REALM, which is not available in MIT Kerberos, resulting in a compilation failure on systems using MIT Kerberos.
 
To address this issue, we suggest guarding the Heimdal-specific code with a conditional preprocessor directive, as shown below:
 
#ifdef HEIMDAL
// Heimdal-specific code here
smb_krb5_parse_name_flags(...);
#else
// MIT Kerberos-compatible code
smb_krb5_parse_name(...);
#endif
 
We implemented the above change locally and were able to compile successfully.
 
Please let us know if a patch can be submitted for this, or if any additional steps are required from our side.
