Ldsview – Offline search tool for LDAP directory dumps in LDIF format

Offline search tool for LDAP directory dumps in LDIF format.

Features

• Fast and memory efficient parsing of LDIF files
• Build ldapsearch commands to extract an LDIF from a directory
• Show directory structure
• UAC and directory time format translation

Config

Config options can be passed as CLI flags, environment variables, or via a config file courtsey of viper. Reference the project’s documentation for all of the different ways you can supply configuration.

• By default, ldsview will look for a file called .ldsview.{json,toml,yaml} in the user’s home directory
• Environment variables with a prefix of LDSVIEW will be read in by the application

Usage

Detailed usage information is available via the --help flag or the help command for ldsview and all subcommands.

Search Syntax

ldsview‘s search mechanism is based on the entityfilter project. Detailed information about search filter syntax can be found in that project’s README.

Examples

• Build ldapsearch command to extract LDIF files from a directory: ldsview cmdbuilder
  • The command will prompt you for any information needed
  • Have the following ready:
    • Directory host FQDN or IP
    • Domain DN
    • User to run as
    • User’s password
• Quickly find a specific entity in an LDIF file: ldsview -f myfile.ldif entity myuser
• Parse UAC flag from AD: ldsview uac 532480
• Search LDIF file: ldsview -f myfile.ldif search "adminCount:=1,sAMAccountName:!=krbtgt"
  • This command will return all entities with an adminCount of 1 that are not krbtgt
  • -i can be used to limit which attributes are returned from matching entities
  • --tdc will translate directory timestamps into a human readable format

Tools Directory

Additional tools and utilities for managing LDIFs:

Makefile: Place the Makefile in the same directory as your exported LDIF and run make.

>> make -j9 LDIF=./my.domain.ldif

This will split and create the following default LDIFs:

• users.ldif
• computers.ldif
• groups.ldif
• domain_admin.ldif
• poss_svc_accnts.ldif
• pass_not_reqd.ldif
• pass_cant_change.ldif
• users_dont_expire.ldif
• trusted_4_delegation.ldif
• preauth_not_reqd.ldif
• password_expired.ldif
• trust2auth4delegation.ldif
