SLAPDN(8C)

💖 NAME 💖

slapdn — bestie, this one checks a whole list of string-represented LDAP DNs against the schema syntax. It's giving DN conformity check energy. 👑

---

✨ SYNOPSIS ✨

/usr/bin/slapdn [-d debug-level] [-f slapd.conf] [-F confdir] [-N|-P]
[-o option[=value]] [-v] DN [...]

---

🦋 DESCRIPTION 🦋

Okay so, slapdn exists to check the conformance of a DN, and it does that based on the schema that's defined in slapd(8) and loaded up via slapd.conf(5). No cap, that's the whole vibe. 🧚

Here's how it moves: it opens the slapd.conf(5) configuration file or the slapd-config(5) backend, reads in all the schema definitions, and then — and this is the main character moment — it parses the DN list you handed it on the command-line. Literally just DN after DN, getting looked at. Periodt. 💅

🎀 OPTIONS 🎀

• -d debug-level — turns on debugging messages at whatever debug-level you specify. Want the deets? Go look at slapd(8), bestie. 🔍
• -f slapd.conf — points at an alternative slapd.conf(5) file, if you're not feeling the default one. 🙈
• -F confdir — specifies a config directory. Now listen closely because this one has layers, okay?
  • If you pass both -f and -F, the config file gets read and converted into config directory format, and then written to the directory you specified.
  • If you pass neither option, an attempt to read the default config directory will be made before trying to use the default config file.
  • And if a valid config directory exists, then the default config file is ignored. Like, fully ignored. Not invited to the party. 💀
• -N — only outputs a normalized form of the DN — the kind of thing you'd use inside a normalization tool. Lowkey incompatible with -P, so don't try to do both. 🚫
• -o option[=value] — specify an option with a(n optional) value. The possible generic options/values are:

syslog=<subsystems>  (see `-s' in slapd(8))
syslog-level=<level> (see `-S' in slapd(8))
syslog-user=<user>   (see `-l' in slapd(8))

• -P — only outputs a prettified form of the DN — perfect for a check and beautification tool, honestly the aesthetic option. 🌸 Incompatible with -N. She's exclusive.
• -v — enables verbose mode. She's talkative. 🗣️

🌈 EXAMPLES 🌈

Wanna check a DN? Run this, bestie:

/usr/bin/slapdn -f //etc/openldap/slapd.conf -v DN

(Yes, that's a double slash up in there — copy it exactly, don't get creative. 😭)
