### NAME

ldappasswd - change the password of an LDAP entry

### SYNOPSIS

ldappasswd [-A] [-a oldPasswd] [-t oldpasswdfile] [-D binddn] [-d debuglevel] [-H ldapuri] [-h ldaphost] [-n] [-p ldapport] [-S] [-s newPasswd] [-T newpasswdfile] [-v] [-W] [-w passwd] [-y passwdfile] [-O security-properties] [-I] [-Q] [-U authcid] [-R realm] [-x] [-X authzid] [-Y mech] [-Z[Z]] [user]

### DESCRIPTION

ldappasswd is a tool to set the password of an LDAP user. ldappasswd uses the LDAPv3 Password Modify (RFC 3062) extended operation.

ldappasswd sets the password of associated with the user [or an optionally specified user]. If the new password is not specified on the command line and the user doesn't enable prompting, the server will be asked to generate a password for the user.

ldappasswd is neither designed nor intended to be a replacement for passwd(1) and should not be installed as such.

### OPTIONS

-A
  Prompt for old password. This is used instead of specifying the password on the command line.
-a oldPasswd
  Set the old password to oldPasswd.
-t oldPasswdFile
  Set the old password to the contents of oldPasswdFile.
-x
  Use simple authentication instead of SASL.
-D binddn
  Use the Distinguished Name binddn to bind to the LDAP directory.
-d debuglevel
  Set the LDAP debugging level to debuglevel. ldappasswd must be compiled with LDAP_DEBUG defined for this option to have any effect.
-H ldapuri
  Specify URI(s) referring to the ldap server(s); only the protocol/host/port fields are allowed; a list of URI, separated by whitespace or commas is expected.
-h ldaphost
  Specify an alternate host on which the ldap server is running. Deprecated in favor of -H.
-p ldapport
  Specify an alternate TCP port where the ldap server is listening. Deprecated in favor of -H.
-n
  Do not set password. (Can be useful when used in conjunction with -v or -d)
-S
  Prompt for new password. This is used instead of specifying the password on the command line.
-s newPasswd
  Set the new password to newPasswd.
-T newPasswdFile
  Set the new password to the contents of newPasswdFile.
-v
  Increase the verbosity of output. Can be specified multiple times.
-W
  Prompt for bind password. This is used instead of specifying the password on the command line.
-w passwd
  Use passwd as the password to bind with.
-y passwdfile
  Use complete contents of passwdfile as the password for simple authentication.
-O security-properties
  Specify SASL security properties.
-I
  Enable SASL Interactive mode. Always prompt. Default is to prompt only as needed.
-Q
  Enable SASL Quiet mode. Never prompt.
-U authcid
  Specify the authentication ID for SASL bind. The form of the ID depends on the actual SASL mechanism used.
-R realm
  Specify the realm of authentication ID for SASL bind. The form of the realm depends on the actual SASL mechanism used.
-X authzid
  Specify the requested authorization ID for SASL bind. authzid must be one of the following formats: dn: name> or u:.
-Y mech
  Specify the SASL mechanism to be used for authentication. If it's not specified, the program will choose the best mechanism the server knows.
-Z[Z]
  Issue StartTLS (Transport Layer Security) extended operation. If you use -ZZ, the command will require the operation to be successful
