This article describes why it may not be possible to connect to Acronis Agent for Linux installed on Debian x64. The article also provides a solution for that.

This article applies to:

• Acronis True Image 9.1 Enterprise Server
• Acronis True Image Echo Enterprise Server
• Acronis Backup & Recovery 10 Advanced Server (Agent for Linux)
• Acronis Backup & Recovery 10 Advanced Server - Virtual Edition (Agent for Linux)

Symptoms

When trying to connect from Acronis Management Console to Acronis Agent for Linux installed on Debian x64 or Ubuntu x64, the following error message is received:

Username or password is incorrect

Cause

At the moment, Debian and Ubuntu x86_64 does not support running 32 bit applications to the full extent.

Acronis Agent for Linux is a 32 bit application and it tries to authenticate against 64 bit PAM module by default.

Solution

1. Please install a minimal set of 32 bit libraries:
   
   #apt-get install ia32-libs

2. Download i386 package libpam-modules and the packages it depends on: libselinux1, libsepol1 from packages.debian.org
   
   • For example, packages for Debian Etch:
     
     • http://packages.debian.org/stable/libs/libpam-modules
     • http://packages.debian.org/stable/libs/libselinux1
     • http://packages.debian.org/stable/libs/libsepol1

3. Extract the downloaded packages:
   
   #dpkg --extract libpam-modules_0.79-4_i386.deb [TEMPORARY_DIRECTORY] #dpkg --extract libselinux1_1.32-3_i386.deb [TEMPORARY_DIRECTORY] #dpkg --extract libsepol1_1.14-2_i386.deb [TEMPORARY_DIRECTORY]

4. Put the extracted shared libraries to /lib32/
   
   #mkdir /lib32/security #cp [TEMPORARY_DIRECTORY]/lib/security/* /lib32/security/ #cp [TEMPORARY_DIRECTORY]/lib/libselinux.so.1 /lib32/ #cp [TEMPORARY_DIRECTORY]/lib/libsepol.so.1 /lib32/

5. Add the path to the extracted libraries to /etc/pam.d/acronisagent
   

   #%PAM-1.0
   auth	required	/lib32/security/pam_unix.so
   account	required	/lib32/security/pam_unix.so
   auth	required	/lib32/security/pam_succeed_if.so uid eq 0

6. Depending on the version you have, restart Acronis Agent for Linux using one of the following commands:
   
   • Acronis True Image 9.1 Enterprise Server Agent for Linux:

   #/etc/init.d/acronis_trueimage_agent restart

   • Acronis True Image Echo Enterprise Server Agent for Linux:

   #/etc/init.d/acronis_agent restart

   • Acronis Backup & Recovery 10 Agent for Linux

   /etc/init.d/acronis_agent restart
   /etc/init.d/acronis_mms restart
