.SH "DESCRIPTION"
.PP
A GSSAPI NTLM mechanism that allows to perform NTLM authentication in GSSAPI programs\&.
.SH "ENVIRONMENT VARIABLES"
.PP
NTLM_USER_FILE
.RS 4
A file containing users and their password hashes\&. The file formats supported are the one used by Heimdal for its NTLM backend, and the samba password file format\&.
.RE
.PP
NETBIOS_COMPUTER_NAME
.RS 4
Set the NETBIOS (short) Computer name used in NTLM packets
.RE
.PP
NETBIOS_DOMAIN_NAME
.RS 4
Set the NETBIOS (short) Domain name used in NTLM packets
.RE
.PP
NTLMUSER
.RS 4
Set the NTLM User name used for authentication on initiation of the security context
.RE
.PP
USER
.RS 4
The default source for the User name used on initiation of the security context
.RE
.PP
LM_COMPAT_LEVEL
.RS 4
The LM Compatibility Level enforced during security context negotiation\&. The default level is 3
.RE
.PP
GSSNTLMSSP_DEBUG
.RS 4
The name of a file to send debug logs
.RE
.PP
GSSNTLMSSP_WB_TLS_CTX
.RS 4
This variable is used to control whether thread local contexts are used for winbindd communication or whether a single process context is used\&. Setting the value of this variable to 0 disables per\-thread contexts\&. Because creating Winbindd contexts is an expensive operation this is used as an optimization in applications that can insure a single thread is used, or already handle their own locking\&. The default behavior is to create a context for each thread, this behavior can be restored by setting the environment variable back to the value 1
