Creating local password policy succeeds with incorrect passwordInHistory value

# rpm -q 389-ds-base
389-ds-base-3.1.3-5.el10_1.x86_64

How reproducible is this bug?:

Always

Steps to reproduce

1. Create a DS instance
2. Attempt creating a new local password policy with invalid values (applicable for both user and subtree)(created pw policies were deleted after every attempt):
   1. # dsconf localhost localpwp addsubtree ou=people,dc=example,dc=com --pwdhistory on --pwdhistorycount -1                   
      Successfully created subtree password policy                                                                  # dsconf localhost localpwp get ou=people,dc=example,dc=com                 
      Local Subtree Policy Policy for "ou=people,dc=example,dc=com": cn=cn\3DnsPwPolicyEntry_subtree\2Cou\3Dpeople\2Cdc\3Dexample\2Cdc\3Dcom,cn=nsPwPolicyContainer,ou=people,dc=example,dc=com                             
      ------------------------------------
      passwordhistory: on
      passwordinhistory: -1
   2. # dsconf localhost localpwp addsubtree ou=people,dc=example,dc=com --pwdhistory on --pwdhistorycount 30                   
      Successfully created subtree password policy                                                                  # dsconf localhost localpwp get ou=people,dc=example,dc=com                     
      Local Subtree Policy Policy for "ou=people,dc=example,dc=com": cn=cn\3DnsPwPolicyEntry_subtree\2Cou\3Dpeople\2Cdc\3Dexample\2Cdc\3Dcom,cn=nsPwPolicyContainer,ou=people,dc=example,dc=com                            
      ------------------------------------                                                                                           
      passwordhistory: on                                                                                                    
      passwordinhistory: 30
   3. # dsconf localhost localpwp addsubtree ou=people,dc=example,dc=com --pwdhistory on --pwdhistorycount a
      Successfully created subtree password policy                                                                  # dsconf localhost localpwp get ou=people,dc=example,dc=com
      Local Subtree Policy Policy for "ou=people,dc=example,dc=com": cn=cn\3DnsPwPolicyEntry_subtree\2Cou\3Dpeople\2Cdc\3Dexample\2Cdc\3Dcom,cn=nsPwPolicyContainer,ou=people,dc=example,dc=com
      ------------------------------------
      passwordhistory: on
      passwordinhistory: a

Expected results

All above values should be rejected as invalid (allowed value range 0-24)

Actual results

All above values are accepted

Additional info

The issue does NOT occur when modifying existing password policy using 'dsconf localpwp set' or when creating a duplicate password policy which actually modifies the existing one
