It seems, if multiple servers supply separate keytabs, then the subsequent kerberos auth request targeted for multiple kerberos servers with separate keytabs and application keep on updating "default_keytab_name" global variable and it causes some of the authentication requests to fail and it throws this error
There is no global variable named default_keytab_name in MIT krb5. There is a krb5.conf configuration variable with this name, but it is never changed by the GSS or Kerberos libraries.
*"GSS-API error gss_accept_sec_context: Request ticket server HTTP/ not found in keytab" *(major code - 186a5, d0000)
This message is a little bit puzzling, because the principal name ("HTTP/") is incomplete, and because the message of this form in the code includes a parenthetical about the ticket kvno.
Using this api *krb5_gss_register_acceptor_identity() *to set the default keytab file for kerberos authentication.
This function sets a thread-specific global variable. It should work to invoke it before each call to gss_acquire_cred(), or before each call to gss_accept_sec_context() using the default acceptor credential. Or:
Can we use any other gss_api to maintain the local context of the keytab file and send this keytab for every authentication request?
gss_acquire_cred_from() allows the caller to specify a keytab name when acquiring credentials. See:
