Comment:
add information about isc-dhcp-server workaround

  
  == Known problems that need to be fixed elsewhere ==
  
-  * isc-dhcp-server-ldap: fails to activate the service, see DebianBug:971275.
+  * isc-dhcp-server-ldap: fails to activate the service, see DebianBug:971275. This seems to happen randomly.<<BR>>In case the DHCP server doesn't work reliably, use the DHCP server packages from Debian 10 (buster).
+   1. Create the file ''/etc/apt/sources.list.d/buster.sources.list'' with the following content: 
+   {{{
+   deb http://deb.debian.org/debian buster main
+   deb http://deb.debian.org/debian-security buster/updates main
+   }}}
+    and run:
+   {{{
+   apt update
+   apt install isc-dhcp-server/buster isc-dhcp-server-ldap/buster
+   }}}
+ 
+   1. To make DHCP downgrading permanent and to ensure security upgrades, create two files to pin the DHCP server packages to the Debian 10 (buster) version.
+ 
+   File ''/etc/apt/apt.conf.d/99-edu-default-release''; content:
+   {{{
+   APT::Default-Release "bullseye";
+   }}}
+ 
+   File ''/etc/apt/preferences.d/99-downgrade-dhcp-server''; content:
+   {{{
+   Package: isc-dhcp-server-ldap isc-dhcp-server
+   Pin: version 4.4.1-2+deb10*
+   Pin-Priority: 1001
+   }}}
+ 
+   1. Once the bug has been fixed, remove the three created files and run {{{apt update && apt upgrade}}}.
+ 
   * libpam-python: porting to python3 needed, see DebianBug:937234.
   * !X2Go doesn't register users with utmp/wtmp, see DebianBug:890517.
   * ldapvi sorts entries alphabetically which can break specific modifications where the order of the definitions is important, see DebianBug:820790.
