Active Directory export script to import into SME Server
I had to migrate users from an Active Directory/Exchange combo to a SME server for temporary disaster recovery event. Here’s the script I wrote to create the export and recreate the users and their aliases in the SME server. The export was done before the disaster of course :) #!/bin/bash #ldapsearch -x -b "dc=customer,dc=com" -h 1.2.3.4 -D "domain\user" -W "(objectclass=user)" > activedirectory.ldiff File="activedirectory.ldiff" #reset files content echo > sme.users echo > sme.aliases cat "$File" | while read line do #concatenate new line to existing info UserInfo="$UserInfo $line" #treat all info if user is finished if $(echo -e "$line" | grep -q '^$') then echo User info finished #treat only users with mail address if $(echo "$UserInfo" | grep -q '^mail:') then #recover data UserName=$(echo "$UserInfo" | grep '^sAMAccountName:' | sed -e 's/sAMAccountName: //' | tr '\[A-Z\]' '\[a-z\]') UserFirstName=$(echo "$UserInfo" | grep '^givenName:' | sed -e 's/givenName: //') UserLastName=$(echo "$UserInfo" | grep '^sn:' | sed -e 's/sn: //') UserMail=$(echo "$UserInfo" | grep '^mail:' | awk '{print $2}' | tr '\[A-Z\]' '\[a-z\]') UserMailAliases=$(echo "$UserInfo" | grep '^proxyAddresses: smtp:' | sed -e 's/^proxyAddresses: smtp:\(.\*\)@.\*$/\1/' | sort -u | grep -vi "^${UserName}$" | tr '\n' '|' | tr '\[A-Z\]' '\[a-z\]') Tmp=$(dd if=/dev/urandom | tr -dc \_A-Z-a-z-0-9 | head -c 4) UserPassword=$(echo "${UserName}${Tmp}" | tr '\[A-Z\]' '\[a-z\]') #print user info echo "$UserName |$UserFirstName |$UserLastName |$UserPassword" >> sme.users #print aliases if any if \[ $(echo "$UserMailAliases" | wc -c) -gt 2 \] then echo "$UserName |$UserMailAliases" | sed -e 's/^\(.\*\)|$/\1/' >> sme.aliases fi #cleanup some shit unset UserName unset UserFirstName unset UserLastName unset UserMail unset UserMailAliases unset Tmp unset UserPassword fi unset UserInfo fi done You can then import all the users and their aliases with the following commands: ...
