=== Search an replace - Replace the content of an attribute - Step by step ===
Execute the search to retrieve all occurrences of the given search filter (ldap attribute and attribute value):
<source lang='bash'>
# Get all child entries.children=$(ldapsearch -LLL -x -s children \ -b "$ldap_base" \
-H "$ldap_server" \
-b "$ldap_base" \
-D "$ldap_bind_account" \
-w "$ldap_bind_password" \
"(${ldap_attribute}=${ldap_attribute_old})"
</source>
# The result will contain something like:<source lang=lang='ldif'>
dn: ou=unsuccessful,ou=templates,uid=5000000,ou=reseller,ou=configuration,ou=b
ackup,ou=services,o=stepping-stone,c=ch
sstMailTemplateResellerFormatSource: txt
sstMailTemplateResellerFormatTarget: txt
</source>
As we are only interested in the dn, we add the following two lines to the search above:
<source lang='bash'>
| awk '{ if (/^ /) { sub(/^ /, ""); } else printf "\n"; printf "%s", $0 }' \
| awk '/^dn: / { print $2 }'
</source>
The final search returns a list of distinguished names, one per line (without the ldif 80 characters per line restriction):<source lang='bash'>
ldapsearch -LLL -x -s children \
-H "ldaps://ldapm.stepping-stone.ch:636$ldap_server" \ -b "ou=services,o=stepping-stone,c=ch$ldap_base" \ -D "cn=Manager,o=stepping-stone,c=ch$ldap_bind_account" \ -w "${ldap_bind_password}" \ "(sstMailFrom${ldap_attribute}=Support stepping stone GmbH <support@stepping-stone.ch>${ldap_attribute_old})" \ | awk '{ if (/^ /) { sub(/^ /, ""); } else printf "\n"; printf "%s", $0 }' \ | awk '/^dn: / { print $2 }'
</source>
We need to create an array of the distinguished names:
<source lang='bash'>
children=$(ldapsearch -LLL -x -s children \
-H "$ldap_server" \
-b "$ldap_base" \
-D "$ldap_bind_account" \
-w "$ldap_bind_password" \
"(${ldap_attribute}=${ldap_attribute_old})" \
| awk '{ if (/^ /) { sub(/^ /, ""); } else printf "\n"; printf "%s", $0 }' \
| awk '/^dn: / { print $2 }'
)
</source>
Finally, we need to loop over all the distinguished names and replace the original (old) content to the attribute with the new content:
<source lang='bash'>
for dn in $children
do
cat <<EOF | sed 's/^ \{4\}//' | ldapmodify -x \
-H "$ldap_server" \
-D "$ldap_bind_account" \
-w "$ldap_bind_password"
dn: ${dn}
changetype: modify
replace: ${ldap_attribute}
${ldap_attribute}: ${ldap_attribute_new}

done

| awk '{ if (/^ /) { sub(/^ /, ""); } else printf "\n"; printf "%s", $0 }' \
