slapcat - SLAPD database to LDIF utility


/usr/sbin/slapcat [-v] [-c] [-k] [-m] [-d level] [-b suffix] [-n dbnum] [-s subtree-dn] [-f slapd.conf] [-l ldif-file]


Slapcat is used to generate an LDAP Directory Interchange Format (LDIF) output based upon the contents of a slapd(8) database. It opens the given database determined by the database number or suffix and writes the corresponding LDIF to standard output or the specified file.

The LDIF generated by this tool is suitable for use with slapadd(8). As the entries are in database order, not superior first order, they cannot be loaded with ldapadd(1) without first being reordered.


Enable verbose mode.
Enable continue (ignore errors) mode.
Include syncConsumerSubentry of the syncrepl consumer in the generated LDIF output.
Include syncProviderSubentry of the syncrepl provider in the generated LDIF output.
-d level
Enable debugging messages as defined by the specified level.
-b suffix
Use the specified suffix to determine which database to generate output for. The -b cannot be used in conjunction with the -n option.
-n dbnum
Generate output for the dbnum-th database listed in the configuration file. The -n cannot be used in conjunction with the -b option.
-s subtree-dn
Only dump entries in the subtree specified by this DN. Implies `-b subtree-dn' if no -b or -n option is given.
-f slapd.conf
Specify an alternative slapd.conf(5) file.
-l ldif-file
Write LDIF to specified file instead of standard output.


Your slapd(8) should not be running (at least, not in read-write mode) when you do this to ensure consistency of the database.


To make a text backup of your SLAPD database and put it in a file called ldif, give the command:

	/usr/sbin/slapcat -l ldif


ldap(3), ldif(5), slapadd(8), ldapadd(1), slapd(8)
