+        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 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>
+         <emphasis>10</emphasis>, <emphasis>0x10000</emphasis>: Even more low-level
+libldb tracing information. Almost never really required.
+    </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>: 0x0070 (i.e. fatal, critical and serious
+failures; corresponds to setting 2 in decimal notation)
+    </para>
