I saw this in the ppolicy pages but was unsure of how to use it? I understand that I can use pwdCheckModule and even how to turn it on, but I am uncertain as to how to actually tell it that we want to have for example, one upper case, one lower case and one numeral. Has anybody done that?
Thanks, Sara Kline

We are using ppolicy to manage the password policy on our LDAP server. It at least checks the minimum length and the minimum amount of time needed before a person can change their password again, but is there a way to get it to check for upper case, lower case, numbers, etc? We need to force our users to make complex passwords.
pwdCheckModule
This attribute names a user-defined loadable module that must instanti- ate the check_password() function. This function will be called to further check a new password if pwdCheckQuality is set to one (1) or two (2), after all of the built-in password compliance checks have been passed. This function will be called according to this function proto- type: int check_password (char *pPasswd, char **ppErrStr, Entry *pEntry); The pPasswd parameter contains the clear-text user password, the ppErrStr parameter contains a double pointer that allows the function to return human-readable details about any error it encounters. The optional pEntry parameter, if non-NULL, carries a pointer to the entry whose password is being checked. If ppErrStr is NULL, then funcName must NOT attempt to use it/them. A return value of LDAP_SUCCESS from the called function indicates that the password is ok, any other value indicates that the password is unacceptable. If the password is unac- ceptable, the server will return an error to the client, and ppErrStr may be used to return a human-readable textual explanation of the error. The error string must be dynamically allocated as it will be free()'d by slapd.

Note: The user-defined loadable module named by pwdCheckModule must be in slapd's standard executable search PATH.
Note: pwdCheckModule is a non-standard extension to the LDAP password policy proposal.
