Updates to our NTLMSSP code: This tries to extract our server-side code out of sessetup.c, and into a more general lib. I hope this is only a temporay resting place - I indend to refactor it again into an auth-subsystem independent lib, using callbacks. Move some of our our NTLMSSP #defines into a new file, and add two that I found in the COMsource docs - we seem to have a double-up, but I've verified from traces that the NTLMSSP_TARGET_TYPE_{DOMAIN,SERVER} is real. This code also copes with ASCII clients - not that we will ever see any here, but I hope to use this for HTTP, were we can get them. Win2k authenticates fine under forced ASCII, btw. Tested with Win2k, NTLMv2 and Samba's smbclient. Andrew Bartlett (This used to be commit b6641badcbb2fb3bfec9d00a6466318203ea33e1)

Changes all over the shop, but all towards: - NTLM2 support in the server - KEY_EXCH support in the server - variable length session keys. In detail: - NTLM2 is an extension of NTLMv1, that is compatible with existing domain controllers (unlike NTLMv2, which requires a DC upgrade). * This is known as 'NTLMv2 session security' * (This is not yet implemented on the RPC pipes however, so there may well still be issues for PDC setups, particuarly around password changes. We do not fully understand the sign/seal implications of NTLM2 on RPC pipes.) This requires modifications to our authentication subsystem, as we must handle the 'challege' input into the challenge-response algorithm being changed. This also needs to be turned off for 'security=server', which does not support this. - KEY_EXCH is another 'security' mechanism, whereby the session key actually used by the server is sent by the client, rather than being the shared-secret directly or indirectly. - As both these methods change the session key, the auth subsystem needed to be changed, to 'override' session keys provided by the backend. - There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation. - The 'names blob' in NTLMSSP is always in unicode - never in ascii. Don't make an ascii version ever. - The other big change is to allow variable length session keys. We have always assumed that session keys are 16 bytes long - and padded to this length if shorter. However, Kerberos session keys are 8 bytes long, when the krb5 login uses DES. * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. * - Add better DEBUG() messages to ntlm_auth, warning administrators of misconfigurations that prevent access to the privileged pipe. This should help reduce some of the 'it just doesn't work' issues. - Fix data_blob_talloc() to behave the same way data_blob() does when passed a NULL data pointer. (just allocate) REMEMBER to make clean after this commit - I have changed plenty of data structures... (This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)

Updates to the NTLMSSP code again - moving the base64 decode fuctionality out of the SWAT code, and adding a base64 encoder.

Fix most of bug #169. For a (very) long time, we have had a bug in Samba were an NTLMv2-only PDC would fail, because it converted the password into NTLM format for checking.

r11573: Adding Andrew Bartlett's patch to make machine account logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes the auth module interface to 2 (from 1). The effect of this is that clients can access resources as a machine account if they set these flags. This is the same as Windows (think of a VPN where the vpn client authenticates itself to a VPN server using machine account credentials - the vpn server checks that the machine password was valid by performing a machine account check with the PDC in the same was as it would a user account check. I may add in a restriction (parameter) to allow this behaviour to be turned off (as it was previously). That may be on by default. Andrew Bartlett please review this change carefully. Jeremy.

Changes all over the shop, but all towards: - NTLM2 support in the server - KEY_EXCH support in the server - variable length session keys. In detail: - NTLM2 is an extension of NTLMv1, that is compatible with existing domain controllers (unlike NTLMv2, which requires a DC upgrade). * This is known as 'NTLMv2 session security' * (This is not yet implemented on the RPC pipes however, so there may well still be issues for PDC setups, particuarly around password changes. We do not fully understand the sign/seal implications of NTLM2 on RPC pipes.) This requires modifications to our authentication subsystem, as we must handle the 'challege' input into the challenge-response algorithm being changed.

Updates to the NTLMSSP code again - moving the base64 decode fuctionality out of the SWAT code, and adding a base64 encoder. The main purpose of this patch is to add NTLMSSP support to 'ntlm_auth', for use with Squid. Unfortunetly the squid side doesn't quite support what we need yet. Changes to winbind to get us the info we need, and a couple of consequential changes/cleanups in the rest of the code.

Updates to our NTLMSSP code: This tries to extract our server-side code out of sessetup.c, and into a more general lib. I hope this is only a temporay resting place - I indend to refactor it again into an auth-subsystem independent lib, using callbacks. Move some of our our NTLMSSP #defines into a new file, and add two that I found in the COMsource docs - we seem to have a double-up, but I've verified from traces that the NTLMSSP_TARGET_TYPE_{DOMAIN,SERVER} is real. This code also copes with ASCII clients - not that we will ever see any here, but I hope to use this for HTTP, were we can get them. Win2k authenticates fine under forced ASCII, btw. Tested with Win2k, NTLMv2 and Samba's smbclient. Andrew Bartlett (This used to be commit b6641badcbb2fb3bfec9d00a6466318203ea33e1)

Changes all over the shop, but all towards: - NTLM2 support in the server - KEY_EXCH support in the server - variable length session keys. In detail: - NTLM2 is an extension of NTLMv1, that is compatible with existing domain controllers (unlike NTLMv2, which requires a DC upgrade). * This is known as 'NTLMv2 session security' * (This is not yet implemented on the RPC pipes however, so there may well still be issues for PDC setups, particuarly around password changes. We do not fully understand the sign/seal implications of NTLM2 on RPC pipes.) This requires modifications to our authentication subsystem, as we must handle the 'challege' input into the challenge-response algorithm being changed. This also needs to be turned off for 'security=server', which does not support this. - KEY_EXCH is another 'security' mechanism, whereby the session key actually used by the server is sent by the client, rather than being the shared-secret directly or indirectly. - As both these methods change the session key, the auth subsystem needed to be changed, to 'override' session keys provided by the backend. - There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation. - The 'names blob' in NTLMSSP is always in unicode - never in ascii. Don't make an ascii version ever. - The other big change is to allow variable length session keys. We have always assumed that session keys are 16 bytes long - and padded to this length if shorter. However, Kerberos session keys are 8 bytes long, when the krb5 login uses DES. * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. * - Add better DEBUG() messages to ntlm_auth, warning administrators of misconfigurations that prevent access to the privileged pipe. This should help reduce some of the 'it just doesn't work' issues. - Fix data_blob_talloc() to behave the same way data_blob() does when passed a NULL data pointer. (just allocate) REMEMBER to make clean after this commit - I have changed plenty of data structures... (This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)

NTSTATUS auth_ntlmssp_update(AUTH_NTLMSSP_STATE *auth_ntlmssp_state,
Merge of server-side authentication changes to 3.0: - user_ok() and user_in_group() now take a list of groups, instead of looking for the user in the members of all groups. - The 'server_info' returned from the authentication is now kept around - in future we won't copy the sesion key, username etc, we will just referece them directly. - rhosts upgraded to use the SAM if possible, otherwise fake up based on getpwnam(). - auth_util code to deal with groups upgraded to deal with non-winbind domain members again.
