<para>
SSSD supports two representations for specifying the debug level. The
simplest is to specify a decimal value from 0-9, which represents
enabling that level and all lower-level debug messages. The more
comprehensive option is to specify a hexadecimal bitmask to enable or
disable specific levels (such as if you wish to suppress a level).
</para>
<para>
Currently supported debug levels:
</para>
<para>
<emphasis>0</emphasis>,
<emphasis>0x0010</emphasis>:
Fatal failures. Anything that would prevent SSSD from starting up or
causes it to cease running.
</para>
<para>
<emphasis>1</emphasis>,
<emphasis>0x0020</emphasis>:
Critical failures. An error that doesn't kill the SSSD, but one that
indicates that at least one major feature is not going to work
properly.
</para>
<para>
<emphasis>2</emphasis>,
<emphasis>0x0040</emphasis>: Serious failures. An error announcing
that a particular request or operation has failed.
</para>
<para>
<emphasis>3</emphasis>,
<emphasis>0x0080</emphasis>: Minor failures. These are the errors that
would percolate down to cause the operation failure of 2.
</para>
<para>
<emphasis>4</emphasis>,
<emphasis>0x0100</emphasis>: Configuration settings.
</para>
<para>
<emphasis>5</emphasis>,
<emphasis>0x0200</emphasis>: Function data.
</para>
<para>
<emphasis>6</emphasis>,
<emphasis>0x0400</emphasis>: Trace messages for operation functions.
</para>
<para>
<emphasis>7</emphasis>,
<emphasis>0x1000</emphasis>: Trace messages for internal control
functions.
</para>
<para>
<emphasis>8</emphasis>,
<emphasis>0x2000</emphasis>: Contents of function-internal variables
that may be interesting.
</para>
<para>
<emphasis>9</emphasis>,
<emphasis>0x4000</emphasis>: Extremely low-level tracing information.
</para>
<para>
To log required bitmask debug levels, simply add their numbers together
as shown in following examples:
</para>
<para>
<emphasis>Example</emphasis>: To log fatal failures, critical failures,
serious failures and function data use 0x0270.
</para>
<para>
<emphasis>Example</emphasis>: To log fatal failures, configuration
settings, function data, trace messages for internal control functions
use 0x1310.
</para>
<para>
<emphasis>Note</emphasis>: The bitmask format of debug levels was
introduced in 1.7.0.
</para>
<para>
<emphasis>Default</emphasis>: 0
</para>
