How to modify IPv4 address using LDIF Files

Question

I need to change an IPv4 address to multiple IPv4 addresses using LDIF file. The original LDIF file which was used to create the HSS ESM is the following:

dn: HSS-EsmImsi=312720000000207,HSS-EsmSubscriptionId=BR-02061969,
    HSS-EsmSubscriptionContainerName=HSS-EsmSubscriptionContainer,
    applicationName=HSS_ESM,nodeName=bnyrgvhss1
    changeType: modify
    add: HSS-EsmUserProfileId
    HSS-EsmUserProfileId: HSS-EsmProfile_APCCI_METERING
    -
    add: HSS-EsmUserIpV4Address
    HSS-EsmUserIpV4Address: 4$10.11.12.13
    -
    add: HSS-EsmMsisdn
    HSS-EsmMsisdn: +1 234 567 8901
    -

Now, I need to do 2 things:

1. Change the IPv4 address (e.g. 10.13.15.17).
2. Modify the HSS ESM User Object Class, so HSS-EsmUserIpV4Address will store multiple IPv4 addresses.

According to Erickson's - ESM LDAP Interface Description this should be done with a string in the following format: [contextId1]$[IPv4-Address1]\n [contextId2]$[IPv4-Address2]\n ...[contextIdNN]$[IPv4-AddressNN]\n.

Legend:

1. [contextId] datatype is uint32.
2. $ is a CONSTANT (US Dollar sign).
3. [IPv4-Address] IP Addresses are dotted-decimal of string datatype, e.g. 10.12.14.16.
4. \n is a CONSTANT (New-Line).

I am new to LDAP and will appreciate any help on how the LDIF file should be to so that HSS-EsmUserIpV4Address will store, for example, the following IPv4 addresses:

2$159.10.1.20
7$159.10.1.21
8$159.10.1.22

I tried to change the LDIF file to do Delete and Add like this:

... (the original code)...
changeType: modify
delete: HSS-EsmUserProfileId
-
add: HSS-EsmUserProfileId
HSS-EsmUserProfileId: 2$159.10.1.20\n7$159.10.1.21\n8$159.10.1.22\n
-

But, it didn't work (no error messages, just no change).

I will appreciate any help, I am here (at work) to stay until I make this happen.

Answer 1

add: HSS-EsmUserProfileId
HSS-EsmUserProfileId: 2$159.10.1.20\n7$159.10.1.21\n8$159.10.1.22\n

First, you're changing the wrong attribute. It should be

add: HSS-EsmUserIpV4Address
HSS-EsmUserIpV4Address: 2$159.10.1.20\n7$159.10.1.21\n8$159.10.1.22\n

and you may have damaged the original value of this attribute, so you need to put it back:

delete: HSS-EsmUserProfileId
add: HSS-EsmUserProfileId
HSS-EsmUserProfileId: HSS-EsmProfile_APCCI_METERING

Second, I don't know where you got this format with \n separators from. I don't see it in the documentation you cited. The normal LDIF syntax for multiple attribute values would be:

add: HSS-EsmUserIpV4Address
HSS-EsmUserIpV4Address: 2$159.10.1.20
HSS-EsmUserIpV4Address: 7$159.10.1.21
HSS-EsmUserIpV4Address: 8$159.10.1.22

Note that this will preserve the prior value starting with 4$, unless you previously used delete: as above.

Answer 2

Thank you EJP, you have put me on the track to the answer and the reason for my previous mistake.

The solution: in the LDIF file use changeType: modify with replace, or delete.

And the correct LDIF file should be:

dn: HSS-EsmImsi=312720000000207,HSS-EsmSubscriptionId=BR-02061969,
HSS-EsmSubscriptionContainerName=HSS-EsmSubscriptionContainer,
applicationName=HSS_ESM,nodeName=bnyrgvhss1
changeType: modify
add: HSS-EsmUserProfileId
HSS-EsmUserProfileId: HSS-EsmProfile_APCCI_METERING
-
delete: HSS-EsmUserIpV4Address
-
add: HSS-EsmUserIpV4Address
HSS-EsmUserIpV4Address: 1$159.10.1.20
HSS-EsmUserIpV4Address: 2$159.10.1.21
HSS-EsmUserIpV4Address: 3$159.10.1.22
-
add: HSS-EsmMsisdn
HSS-EsmMsisdn: +12345678901
-

This will delete a specific value from the attribute and add 2 others:

dn: HSS-EsmImsi=312720000000207,HSS-EsmSubscriptionId=BR-02061969,
HSS-EsmSubscriptionContainerName=HSS-EsmSubscriptionContainer,
applicationName=HSS_ESM,nodeName=bnyrgvhss1
changeType: modify
delete: HSS-EsmUserIpV4Address
HSS-EsmUserIpV4Address: 2$159.10.1.20
-
add: HSS-EsmUserIpV4Address
HSS-EsmUserIpV4Address: 1$159.10.1.23
HSS-EsmUserIpV4Address: 2$159.10.1.24
-

The following code will delete all instances of the attribute and add the attribute again with 3 other values:

dn: HSS-EsmImsi=312720000000207,HSS-EsmSubscriptionId=BR-02061969,
HSS-EsmSubscriptionContainerName=HSS-EsmSubscriptionContainer,
applicationName=HSS_ESM,nodeName=bnyrgvhss1
changeType: modify
delete: HSS-EsmUserIpV4Address
-
add: HSS-EsmUserIpV4Address
HSS-EsmUserIpV4Address: 1$159.10.1.25
HSS-EsmUserIpV4Address: 2$159.10.1.26
HSS-EsmUserIpV4Address: 3$159.10.1.27
-

I found this on How To Use LDIF Files to Make Changes to an OpenLDAP System.

Thank you for @EJP for his HUGE help.
